I found this for sale on craigslist last night a picked it up today. Its a neat little amp, true bedroom volume, sounds good, surprisingly clean and takes pedals pretty well (it liked my tube screamer and tone bender, less so the rangemaster and big muff). Unfortunately, its going to be a bit more of a project than I expected. It is completely original and in good shape, including the original tubes. Which is where the trouble begins, this is a version of the common "american 5" circuit that used line voltage without a power transformer. I though this version was build from the factory with an isolation transformer since it was a later model and was referenced as being that way here and on an old TDPRI thread I found on one. Upon opening it up, no such luck... It has an OT and an isolation transformer for the 12au6 (seems like they could have gone the extra mile and isolated the whole thing instead) but the rectifier and ground are connected directly to the mains! This one is also lacking a fuse and of course doesn't have a modern grounded power cord. So, in addition to needing to replace the power cord and that big red firecracker cap (which is notable for containing both the filter caps and the cathode bypass cap for the power tube) I need to install an isolation transformer (also possibly a bridge rectifier since the rectifier tube is half wave) and a fuse holder. The back panel says 117v at .22 amps, so I figure a 35va iso transformer should do the trick (if using a bridge rectifier). In any case, the whole thing is a bit more work than I bargained for when I bought it, but it should be an interesting project and it really is a great sounding little amp as long as it doesn't shock you when you plug into it .
