Hello, i am a new member with a dead Dynaco Mark III tube amplifier. Many years ago when my amp died the retailer told me the rectifier tube needed to be replaced and that they did not have another one in stock. The quickest and best thing to do, they said, was to change the amp to solid state rectification. The modification made the high notes more harsh to my ears and the amp mod. eventually caused enough heat to melt or damage the insulation on the amp's wires so that the fuse blew. Now I want to start using the amp again. Should I attempt to change the wiring back myself or try to find someone to do it for me? I am not an electrician or electronics tech.

As usual the old wiring you have are stranded wire, now make sure the new wire you will place be Solid hard wiring awg 14 or 12, if you use stranded wire again dont made worth the expense IMO.

Call Frank van Alstine 651-330-9871, His knowledge of these amps is deep and goes back to his says selling and servicing them as a Dynaco dealer. IIRC he is NOT a fan of SS rectification for these but can recommend alternative tubes for rectifier. He may see this but usually recommends a phone call.

Lots of wires in those amps; which ones are fried? The ones connected to the rectifier? Posting a photo may help him if he sees it or someone else here may have ideas too.
