Still plodding ahead on my Reverberocket restoration. Chassis is out of case and all tube sockets cleaned and capacitors checked. First step is to replace the two large 20 mfd caps located on each side of the chassis - checked values showed some drift. These caps are on order from Antique Electronic Supply. The large can (combined) cap, which I first thought was a rectifier tube, actually checked ok regarding capacitance values, with very little drift. A few other caps are questionable but I'm progressing in a step-wise manner due to my amateur status as an electronics tech. There is no evidence of any resistors overheating, all components visually look ok, and all solder joints look good.
According to the chassis date code of 001478, this amp was manufactured in January of 1965. Everything is cleaning up nicely with the chrome plating on the chassis being free of any defects...truly a beautifully made amplifier.
A couple of additions - I measured the speaker resistance with leads disconnected and got a consistent 8 ohms dc.
This amp has a solid-state rectifier. Circuit is designated R-12-R-M and is very close to the R-12-R-T schematic.
