I am rebuilding/ converting a Motorola console amp HS-621 year 1957( golden voice) all the resistors and caps where cut out before I got it. I have the Sams and Beitmans. I am looking for anyone that drew up a wiring layout or has good photos of one thats been restored underneath. Im trying to stick close to the original but its hard to understand all of the actual wiring layout from the schematic the Sams (from Sams website) doesn't have the greatest scan of the underside.Also some large caps from the original Sams cover some sockets.
Thanks for any help.
I cleaned it up/ de-soldered cut out parts and started the build here is what I have so far. Pretty clean unit. Has nice iron on it. I replaced the 2 12au7 sockets with new ones of better quality. Added fuse, indicator light, switch and IEC socket (fun) . Also I removed the second RCA jack input I am going to use the input next to volume pot. Also I plan to use all metal oxide resistors.
