I have done several of these,
replace the 1st pre-amp tube with a 12at7, increase the anode load resistors on the 1st pre-amp tube to 270k, replace the coupling caps to 0.1mfd, replace the speaker, replace the el84s with jj or mullards, replace the el84s tube bases with ceramic types, as they WILL cause future problems, increase the bias voltage to the el84s as they are run much to hard (beyond there ratings) leading to short tube life,

I am in the U.K, & can do this work for anyone interested,

Dave
