A fried hard drive has canceled part two of the look at the circuitry of the Estey T-12, so we move right along.
This is a 1958 Stadium 400-T, a rare bird that is difficult to dig up documentation for, either online or in books. As can be seen from the slightly warped rear panel that adjoins the control plate, the wood on the amp is plenty thin.
I’ve never seen nobs like these and they are either plastic or perhaps bakelite. The handle and its mounting look to be straight off a piece of late 1950’s luggage.
The brushed steel panel is somewhat like that of a vintage Fender but the lesser grade of metal doesn’t have quite the same shine. There are three inputs but it’s the middle port that provides the highest gain.
