Encontré este grupo gracias a un foro, soy dueño de un 500 supreme se dañó el potenciómetro principal de volumen, es muy complejo repararlo, ningún técnico quería tocarlo, ese repuesto no se consigue, por años lo estuve usando como amplificador conectado a un pre amplificador, hace unos días encontré un técnico que se atrevió a intentar arreglar ese potenciómetro que es de 8 etapas, espero pueda solucionarlo ya que ese potenciómetro al estar dañado la máquina de protege y no da volumen, espero sus comentarios

I found this group thanks to a forum, I own a 500 supreme, the main volume potentiometer was damaged, it is very complex to repair, no technician wanted to touch it, that spare part is not available, for years I was using it as an amplifier connected to a preamplifier, a few days ago I found a technician who dared to try to fix that potentiometer which is 8 stages, I hope he can fix it since that potentiometer when damaged protects the machine and does not give volume, I await your comments
The volume pot is easily cleaned similar to any square ganged sealed pot. You loose. The wafers enough to clean if you want to do it the easy way. The hard way involves complete disassembly. I went the easy way and it worked fine.
