Came with an assortment of tubes. The power tubes are mismatched brand (I imagine not matched for bias, Gm, etc). The “ECC083” does not have a brand marking but the internals look like nice quality construction. All tubes are visually fine.
The fuse in the amp is a 3A fast blow type. Back panel calls for 2A.
Bolt heads show it’s been opened up before. We’ll see why later.
Very clean chassis. Sockets are in decent shape.
Gotta love vintage point to point and turret/eyelet construction. Again, nice and clean here. Fiberboards are in good shape, minor warping from age/storage. Cloth covered wire. Rectifier diodes and bias network in the top of the pic will be replaced.
Power filter caps. The larger orange cap on the right appears to be the reason it was opened up in the past (probably a long time ago). Non-original, non-spec, not that it matters. These will all be replaced.
Old tag. Not sure about production number. Maybe May of 1967?
