I am restoring a Japanese Teisco mixing amplifier from the 1970s. It's a solid state 5-channel mixer with 16ohm speaker outs and a line out. Amongst other problems, I have discovered a couple of the bridge rectifier diodes have shorted out.
Here is a photo of the diode bridge:
Now i am trying to find a suitable replacement for these diodes as they have no markings. I cannot find any circuit diagrams or info on the unit at all. The diodes and the PCB both have no markings. If we can't identify this component ~ Is there a common equivalent used for typical solid state amps from this time? Surely. The filter capacitor is 2200uf 63V. Would a 1N4007 do the job?
Thank you in advance, Looking forward to a reply.
