montesquieu's STA100
As well as some other STA100s that are quite a bit further ahead than this, montesquieu has sent in his STA100 for full restoration
As far as original STA100s go his wasn't in too bad nick as it had previously had been serviced to a good standard, though the intention was to always have it rebuilt and improved in a few areas. While the STA100 is a good amp there are many sensible ways it can be improved in terms of reliability.
Flying leads are visible in the 2nd pic due to output transformer development - Tom's amp was a convenient guinea pig ;)

Oops. This explains why one valve wasn't biasing up at all!

First thing I needed to do was strip down the amp.
Sadly someone had punched some large holes in the chassis where the binding posts go, so this had to be rectified. Luckily I know a friendly local engineer who did me a favour here! Some plates were welded in and ground flush (it's flatter than it looks). All that is needed is holes drills for binding posts. Clearly the whole chassis will be blasted clean and powder coated, I don't think Tom would be too pleased with the current finish ;)
