as usual what I see here at Audiogon is the manufacturer of Audio nor the official repair centre is not willing to give you any info about parts , or technical info.I wonder if this against eq European rules .It is strange because in the automotive industrie you can get the software of cars , buy parts at shops not related to the brand .I'm not talking about losing your garanty , thats another question.But getting the info for which Tsushima1 is asking he has to wait until somebody will be so helpful to measure or let measure the data he wants.( I 'm sorry for you , I have the REF3)
ARC Reference 5SE Circuit Voltages
Whilst I fully appreciate that ARC Central's policy would be to forcably lobotomise anyone outside of the program who obtains 'classified' information in respect of company circuit diagrams I would be most grateful should anyone be in a position to advise me as to the relevant circuit voltages and loadings of the 6550 valve within the power supply section of the Ref 5SE ?
