Hitachi HCA and HMA 7500mkII. I hear some people like those big VUs ... :cleansound:

Preamp completely recapped (lots and lots of caps, including seriously difficult to find bi-polar)
Power amp completely refreshed - all caps, all resistors of the specific type (brand) that we found have ALL drifted badly, all small signal transistors, original Hitachi 2SJ49/2SK134 lateral FETs in the output. Power amp is a true 2-mono blocks in one chassis design. So much so that it has 2 world-voltage selectors - one per PSU (per channel)  :faint:

Sounds mind bogglingly good and it has tons of real power.
