Found in pieces, filled with filth, cord cut, cabinet veneer peeling. Restored it to a very, very good condition. Checked caps, cleaned pots. Slowly, cautiously bring each subsection up limiting current, checking voltages at every step. Replaced selenium bridge and increased R to 30ohms, 12ax7 string at 37 volts now at 46 volts (<12v x 4). Output 7189 tube started to arc, apparently ionizing leakage; quickly powered off, then slowly again. Ordered set of four russian 6p14p tubes, just in case. Set tube balance. Still unstable, but finally able to hear static and hum! The hum only through open phono input with max volume; no hum on high level tuner inputs! More cleaning, gluing veneer, restaining, and it now is very quiet and stable and pretty! My first tube amp, my wife and I listened to it, and truly, it was almost a religious experience! Anyhow, got this and an Akai 4400 Reel to Reel for $15, a bonus free box of components and a first edition of Ghirardi's "Modern Radio Servicing", 1935.
The only thing is it doesn't have a bottom metal panel, and it needs an oem power knob (these are the same as the LK series too?). Does anyone know who may have this kind of thing? It would be a shame to not complete the job,such a survivor. Thanks for the read!
