What to do with gutted Heathkit A-9

[BrianS]

Several years ago (5? 6? ) I bought this Heathkit amp at an antique store.  My thought was to make it into a guitar amp.  Not knowing or caring much about some of the vintage parts inside (other than the tubes) I gutted it & chucked pretty much all the old components.  My only concern at the time was that it had nice tubes, beefy looking transformers & a useable chassis.  Then, as often happens with projects like this, it got shelved for about half a decade.

Now, I'm contemplating what I can do with this thing.  I did a search & found one thread where someone rebuilt an A-9c into a guitar amp, but it seemed very troublesome & the thread was confusing to me.  Basically it was no help.

So, I'm either going to rebuild this back to original specs (It came with original owner's manual/instructions/schematic), or turn it into a guitar amp.  I'm looking for suggestions, experiences, advice, etc...

Thanks

You might build it back into what it was, a hi-fi amp.

You might build it back like it was, but adapt for guitar use. According to the sensitivities listed for each input, the Mic & Moving Magnet (MM) inputs would be a bit too hot, while the Ceramic input would be a bit too clean. I'd leave the last 12AU7 and the entire output stage the same (as well as the power supply), then look at what you might do with a 12AX7 and 12AU7.

The original tone circuit is likely useful, but will probably need values changed to work best for guitar.
