Contact Signature Sound, they have taken over the service work for Joule, Rich may know someone who is selling or he may have a pair in on trade.
Interest in Joule Electra VZN220 amps?
I have a friend with a pair of "Rite of Passage" VZN 220 OTL amplifiers he needs to sell.They are built with "musicwood" and have matching Variacs for slow turn-on. I have no idea what price these would sell for. Does anyone have experience selling or buying these?
