Hello
I recently bought a nice Ampex 600 chassis, I gutted the electronics and I intend to rebuild it fresh from the ground up with some tweaks. I want to be able to use it as a mono mic preamp, or stereo line amplifier. I also want to keep the main power transformer and the 5,5 henry choke.
I have bought some iron too, a pair of Altec 15335A for the line inputs, and a pair of Altec 15095A for the line outputs, and I still have to choose the mic input transformer. I have a pair of Gates mic transformers coming from a Yard tube console, maybe I'll use one of these, maybe another one. UTC A10 & 11 are a bit expensive for my budget...
I made a first version of the schematics, merging the schematics from the 600 and 601 models and doing some tweaks.
What is your opinion on that?
My main doubts are the PSU section (untouched for now on), I now it won't behave the same way without the same number of tubes and different tube power consumption etc. But I'd like to keep it tube rectified. And the Right side line input (I don't know if it will behave like the left side)
Any help is welcome
Linked is the schematics I have for now on...
Thanks a whole lot
Thomas
