Hello

Can some kind person please point me at an on-line copy of the circuit, or
service manual, for the Heathkit S-99 amplifier? (Valve stereo 9 watts per
channel, early 1960s.)

TIA

Thank you - but I haven't been able to find it on this site. Whereabouts
exactly should I be looking?

Hmmmm, it's possible it hasn't been added?

I just mentioned BAMA because they are the best remaining source for
Heath manuals.

Maybe similar to SA-2?

Not very, no, but thanks for the link. The SA-2 is interesting in its
own right.

The S-99 uses pairs of ECL86s in the output, although still I think
ultra-linear, with different feedback arrangements and solid-state
rectifier and various other differences in the earlier stages.

I am seeking a circuit as I want to give it a thorough look-over, and
I'd like to be quite sure about what I am dealing with before offering
it on eBay, although it actually sounds very nice and smooth. It's a
nice one that looks to me to be obviously factory-built. (I gave it an
inadvertent soak-test when I had to be rushed into intensive care and on
coming home a week later it was still sitting there playing Radio Three
perfectly happily, cool as a cucumber.....)

Thanks anyway, Tom
