In reply to RFBurns. How are a 6AL5 dual diode used by heathkit for the TX-1 transmitters clipper circuit.

I wonder if one could use a tube with 2 diodes and a triode in this circuit to replace the first tube and the diode pair? Something like a 12AV6 (1/2 of a 12AX7 + two diodes) or something similar… Perhaps this approach could be used to eliminate the entire front end of the circuit as shown and still provide similar benefits…

Hi Chris, Good news

I found in web blog about signal clipper that hum radio guys wrote
ORBAN specified diodes those used in signal clipper eqmt

Those basically low voltage switching diodes
But for the audio signal clipper ORBAN specified below

Multi band clipper diode > 1N4148 or 1N914
Safety clipper diode > 1N5711 or 1N5712

Got another info from custom stomp pedel maker
below is what he said

Yes 1N4007 or 4006 can be used
As long as if it’s sound good to your ears
If sounds bad or distort or squished too much
You might have to change around with other

What about Coil trans next to R1?

no, i have not,,, it’s on the list though! It would be at the very least an interesting ‘colour box’ for the studio. c.
