Great save re: the record transfer from WWII
Had a reel to reel in high school/ recorded regularly off the TV( American Bandstand). Hooked up wires to the tv speakers and jacked this into the tape recorder. Still have the tapes/ brought the tape recorder to parties as a music source. I guess I was one of the first DJs.
check out this weekend’s edition of the WSJ for an article/book review about Alan Lomax:

Hi,
I’ve discovered on a fly market a “Brush Sound Mirror” reel to reel, probably a BK401.
It seems to be in good state. I want to restore it as carefully as possible.
My work should be more easy if I had some technical information about the machine.
Do you think that I could find the user manual, service manual, schematics, etc… ?
Where ?
Thank you very much if you could help me to find sources of information.

Schem: http://www3.telus.net/burnabeans/studio_news/soundmirror/fig644.jpg
interested in the op6 copy you made.could i get some schematics for the build
Hi Jamie. thanks for writing. as i explained in the article, the unit is simply a combination of the BA2 and the OP6. I don’t have a complete schematic drawn; but you really don’t need one… just join the input stage of the the BA2 (up to the output wiper of the volume pot) to the OP6 (from the grid of stage 2 on out). be sure to add a 1M resistor from the grid of stage 2 to ground; isolate this from the volume pot with a 1K resisitor. You can use the power supply from either unit;you should also use DC filament supply. Good luck. the piece sounds really awesome; it’s worth the effort.
OH BTW also… since it is a 90DB gain preamp… there is SOME hum at high levels… so would recommend using the Jensen triple-sheilded inoput transformer rather than the basic 115 transfo that i used.

how many IPS does the Fostex A-8 (8track) record I have tapes i want to digitze and all studios are asking me what speed it was recorded at.
You can get all the tech info on the A8, including IPS, by downloading the PDF that I uploaded on the post. the link is:

good luck!
Have an interesting horn, not sure if it came from gramophone (cast), or logging horn. Thank You I will send pics if you give the go ahead
Hi,
I just came across your terrific site while trying to find some information about an old microphone. I have an Electro-Voice model 664 serial number 181415. I’m trying to buy a desk stand for it. Apparently something called the stud size changed in 1968. If I have the pre-1968 version then I can use a 418 base. Otherwise, I need the 419. These are not cheap. They’re running between 75 and 150 dollars on eBay, so I want to make the correct choice. Anyway, thanks in advance.

Hi shawn. I don’t have an idnex of EV serial numbers. Can anyone else help shawn out? I can tell you that in my life i have only see 3 different sizes of professional-mic thread-sizes, and couplers to adapt them all are still avail cheaply; try BSW, marketek, full compass, etc… good luck…
I can’t believe a site like this exists! Older gear has fascinated me ever since I found a Foxx wah and Fender Bandmaster amp in a barn about 25 years ago. Old gear takes me to another era. Thank you so much for this site!!
I have a pair of Bozak ls330a speakers that have a 1 and 2 on the back for speaker hookup. My question is which one would go to the + or – on the receiver or amp
Mark: I have used the following technique in the past. You will need to visually see the actual speaker cone in order to do this. Attempt at your own risk.
SOURCE: http://www.thegearpage.net/board/archive/index.php/t-663468.html
“An old trick is to take a 9V battery and connect it to the guitar speaker (9V won’t hurt the speaker if connected momentarily—–connect each pole “+” and “-” to the speaker connections—i have a 9V speaker clip with two alligator clips made up for this purpose) — the speaker will move In or Out—- the speaker connection that is connected to the “+” 9V battery pole, when the speaker moves Out (away from the magnet)— this is the Pos speaker connection.
The same 9V battery trick can also be used to check if multipule speaker cabs have all their speakers connected “in phase”— connect speaker cable to cab and then connect 9V to the Tip and Sleeve connectors of the speaker cable plug—-see if all speakers are moving in the same direction—–then put the back panel of the 4×12 cab on and jam out…………………..gldtp99″
I have used this idea with a 1.5 volt “D” cell & “C” cell also. If you cannot get access to the speaker cone itself, try taping a piece of tissue paper of some kind onto the front of the speaker grill. Then momentarily touch the positive side of the battery to the wire. You may have to do this several times to be able to see the tissue paper move, however when it moves “out” a little, you will see it, and there you have the + connection! Good luck!
HI since 1983 I have. A recording studio, and its still my livin’ I workt for manny years with an DDA console, the sound is O K, bud now mi console is starting to make strange noises, and a lot of hiss, I wont to by a new one, but DDA is not longer available.

Hi I’m Frank Santa.saludos from Barcelona, I have some time here in my workshop a strange and beautiful machine that we know very little that comes from the EMI studios, a noise suppressor, full of good Brimar valves type 6060, Mullard logo 50′s ECC88-pin gold, Marconi EB91, EAA91 and several Mullard 0B2, transformers manufactured by EMI type RSA12B, RSA28C for years looking for information about this device works properly, so if it were possible to work with in the context of current recording studio if anyone has information about this I would appreciate knowing the make.
Thank you very much for your time.
Best regards. -
Frank Santa.

Hi Chris,
Just wanted to say thanks for very interesting content on this website. I’m an audio student in Vancouver, Canada, and I’ve found your articles to be very relevant and often inspiring in my learning of the recording process. Thanks again!
Cheers,
Tim
Thanks
Tim. Keep
Comin by, there’s gonna be plenty more. C.
need to buy one of those fairchild record cutting lathe
Rudy
Have a Fairchid 641 Stereo cutter system with a VanEpps overhead
carrier with a regulated Bodine Variable Pitch drive, a Fairchid 750-2
turntable (33,45), Fairchild console stand. The 641 system (Serial #2) was retired in 1983, in great working order. Have Lp album pressings to
attest to its perfomance. It is in storage and was never replaced.
would be interested in talking with anyone – dexwitt@comcast.net
I’m the original owner of a pair of JBL L45 Flair speaker systems & would like to sell them at a fair price directly to someone who would appreciate them.
The aluminum speaker frams are intact. The foam, as with all of them, has disintergrate but I had them covered with auto speaker material.
I’m in the Tampa, Fl area. My email address is albrand2000@aol.com
Hi I have built your Marantz 7 preamp phono and line stage. The rest of my system is Marantz CD 10 Technics SP 10 MK2 with Jelco tonearm and Denon 304 with sowter step up transformers. My power amps are Western Electric 91a with 300b tubes, and speakers are Lowther PM7A in Mauhorn 1v horns. sounds very musical.
Regards Peter.
that is great Peter! I am about to start my second Marantz 7 phono pre now… once i get a couple of other things off the bench. c.
I have an Kustom K-150-1 amp, serial #90905 and I need to replace the speakers in it. Does anyone know where I can find the proper specs for the speakers I need. I got it when I was trying to recover from a severe head injury in 1977 (used) and it has an immense amount of sentimental value to me and I want it to be “right”. I would really appreciate any help. Thanks.
YIPPeeeeeeeeeeeee!!!! Hot Da@# Dog!!!! Finally!!!!….thankx a mil Chris

Buongiorno,
sono in possesso di due diffusori “university Sound” modello “brillance” funzionanti.
C’e’ qualcuno che può essere interessato? Quanto può essere il suo valore? A richiesta si invia foto degli stessi.
Ringrazio per l’attenzione cordiali salutiù

Hi Chris, I thought I’d mention that I’ve been having trouble loading the pages. Seems a few weeks back the pics became very enlongnated. Loving the stuff your posting. I’m a Hammond organ nut. I wondered if you’d ever poked around with them?
hi keith. thanks for letting me know. Yeah WordPress changed a bit recently re: file uploads, and it now seems to want to default to incorporating full size dimensions rather than default scaling the images to fit the wordpress column width. It sucks. I’ll try to be more diligent about this. on my Mac it looks fine, so i had not realized. so thanks i appreciate the feedback.
I have two hammonds – an L101 and an A100. Both are tube/tonewheel organs, the A100 is a B3 with built-in speakers and reverb system, otherwise identical i believe. L101 is a ‘spinet’ model but it has this great psych-y effects board built in that makes it still a worthy contender. I’ve worked them a little bit, changed a few tubes, caps, switches, etc., but nothing major. They both work great and use them on most projects at Gold Coast. c.
In the mid 1960s (1963-1965) I purchased a Pilot Gerard phonograph Model #XKE 1000 Suitcase carrying design. I still have it in my possession and it is in excelent condition. I could not find this model on any of your web pages and Iam wondering if this products has value to a collector.
Sincerely, Kurt Gottschalk
Hey there,
Big fan of your blog and your knowledge of all things old and audio. I was wondering if you did repairs? I have a Moog Parametric EQ that needs to be revitalized? The last guy didn’t have the proper testing instruments. Something you might be able to help me with? I’m located in Bridgeport.
hi matt. i specialize in servicing vacuum tube-based equipment. I could prolly fix yr moog but i might not be the fastest or cheapest option. you can find plenty of dudes who can repair solid state stuff… many people around here use Audio Nexxus in milford for that sorta thing. See ya round town …. c.
Thank you, Chris! I’ll give them a call. I also have an Altec 1567a with the transformer extender that could use some TLC. Do you have a good source for reasonably priced Altec transformers? What are your rates for repairs?
Hi there. Please email me at Chris (at) preservationsound dot com. Thanks! c.
