Hello Bannister,
Thanks for your response.
I finished up getting the info from Quad about just dropping a new set without the need to re-bias. We brought a QUAD set of Svetlana Winged C - Crio treated. Very Impressed.
The amps don't actually belong to me, but I've been loaned them for a few months while a friend is OS and enjoying them immensely.
The 6SH7s are Philips in one amp and GEC in the other. Not sure about the need to match? Not much on the web about this.
Do yours run hot. I seem to be getting a lot of heat building up in the main transformer (casing) - one more than the other.
Also they have 5AR4 rectifier tubes not the 5UAG as listed in the specs. I queried QUAD in the Uk about this - and although they've never used these, they said there shouldn't be a problem.
Peter
