[QUOTE="Ampdog, post: 397634, member: 144"] Maestro, Before going replacing things in general until you strike rich or burn out something, you should have things tested in an orderly fashion. Not to be over-sceptical, but the replaced OPT .... how good is that - an otiginal? At worst you may already have lost an OPT in the sense that it shorts at random. The EL34s were a stupid move to begin with. If you are who I think you are, you have a PM. Late note: While the subject came up: For those with an interest: Kindly beware of using EL34s in a Quad II; the subject has been covered on numerous occasions. A more than adequate replacement for the KT66 is the 6L6GC (less expensive to boot) or some of the ruggedised 5881 versions. The EL34 has different characteristics and should be used according to recommendations. Those do not include indifferent "rolling". [/QUOTE]
