Thanks hampamp,
I've got a quote on the valves at a pretty good price, so will go ahead with what I said. I do have a meter that measures capacitence, so I will get busy tomorrow measuring and cleaning etc. Jesstaa I will recheck the valve sockets as you suggested, thanks mate. By the way, the cost of quad boxes has always been ridiculous even back in the 70s and 80s( the 80s is when I worked in music retail ). There have been some excellent local boxes produced but even these were really expensive. So much for the excuse of " they are so expensive because we are shipping air" I would loved to have a had a dollar for every time a wholesaler said that to me. In 1990 when I was working in retail a 1960a rec. retail was $1195.00 AUD. At least they have come down a couple of hundred since then, yeah I know that's cold comfort. Anyway thanks for all your help it has been invaluable, I hope to be able to help out others as you guys have helped me so far . This is a great forum and people like you make it what is. Will stay in contact
All the best
