Old Thread, but an interesting comment. I worked for Heil back in the day, the part numbers of transistors were never a secret or marked out.
The outputs were mostly Motorola MJ15003, later years they were RCA423. And they only blew up due to mis-use..
The amp itself was designed by audio pioneer Don Hartwig for Heil.
RIP to both Bob and Don, great guys…

BOB AND I WERE BOTH FRIENDS FOR OVER SIXTY YRS. WE WERE BOTH HAM OPERATORS, (HE; K9EID, AND I K9GAQ IN THE SIXTIES, KF9F NOW). – JOE WALSH IS A HAM WB6ACU, AS IS RONNIE MILSAP WHO’S CALL I HAVE FORGOTTEN-.
WE BOTH PLAYED KYBDS (BOB WOULDNT PLAY ROCK & ROLL AT ALL).
HE WAS ONE OF THE FEW WHO COULD TUNE THE PIPES OF A PIPES ON A PIPE ORGAN BY EAR. A VERY MUCH GENIUS, IN THE FIELD OF BOTH SOUND / AUDIO AND ELECTRONICS. (NICKNAMED “HIGH TECH HEIL” ON A LOCAL TV SHOW.. HE WAS SENT SIXTEEN ANTENNAS BY A COMPANY IN THE U.K. TO ASSEMBLE AND DEVELOP A PHASING NETWORK FOR THEIR PERFORMANCE. BOB DROVE A 1956 THUNDERBIRD, WITH A KILOWATT, 144 MHZ AMPLIFIER IN THE TRUNK.
ON MANY OCCASIONS, I WOULD TALK TO HIM AS HE WENT FROM HIS GIG AT A ST. LOUIS UPSCALE RESTAURANT TO HIS HOME IN MARISSA. I WILL GREATLY MMISS HIM, A WONDERFUL PERSON, HE ALWAYS HAAD TIME TO CHAT WHE WE MET AT AMATEUR RADIO GATHERINGS OF TEN OR TEN THOUSAND HAMS. AS HIS ILLNESS INCREASED, WE STAYED IN TOUCH VIA EMAIL FROM HIS HOME IN BELLEVILLE, IL.
THE LAST GIG HE HAD THAT I AM AWARE OF WAS PLAYING ACCOMPANIMENT TO THE OLD TIME BLACK AND WHITE MOVIES FROM FILM HISTORY, AT A THEATER IN BELLEVILLE. I WILL MISS BOB AS AN ELECTRONIC WIZARD, A FELLOW HAM RADIO OPERATOR, MUSICIAN, AND TRUE FRIEND. AS WE SAY IN HAM RADIO SPEAK, ‘73 OLD MAN.

I recently acquired 4 “White mighty” monitors 2 marked 8 ohm and 2 marked 16 ohm , the horns on a couple have blown resistors. Any idea on part # and where to buy?

Just picked up a Heil Sound Ohmega stereo amplifier Model number 200. I’m assuming it’s a 200 watt stereo amplifier. Not a whole lot of information on it.

A few months back I found a Heil Sound mixer at a flea market for 30 bucks. I knew that the guy selling it had no idea what he had, so I picked it up immediately. I brought it home and turned it on, and of course it doesn’t work. But I found your post and discovered it was a HM 88! I emailed Heil Sound to inquire about the mixer and maybe to get some insight on how to go about fixing it. I received an email from Bob Heil himself and he spoke highly of the mixer, and mentioned that it was WAY ahead of its time. So figured i’d let you guys know that I found one!

Bob is more famous in ham radio circles than in audio today. His Ohmega amplifiers were revolutionary, but blew up spectacularly, (and he wouldn’t tell anyone what the transistor part numbers were) and his RCA lookalike mics are great props from a distance but are not even in the same universe as the really good AEA Wes Dooley ribbon mics. In other words he’s kind of a schlockmeister, like a lot of ham radio people once the Art Collinses died off.
