Still toying with the idea of new power tubes for my Prima Luna Mono blocks and it's looking like the Genalex KT 88 Gold Lion jobbies. I was just wondering if anyone had tried one of the Watford Valve upgrade kits which include the above plus Harma driver valves? I think Harma are their own brand made in China?

Not had an 88 amp, but do have a set of 77’s for my Unison Research S6 which are very good. What are your front end valves? Sure you could do better than the Harmas..

When I had an el34 amp I found that changing the pre valves made more difference than changing power valves.

I know of two occasions when one (or more) of a set of matched valves from Watford valves has gone bad that the company have not really wanted to know, or do anything. So customer service can be poor.
Hotrox in Nottingham have a good reputation if you are interested in an alternative supplier. I have used them in the past.
