RT100 Pre Amp Valves
« on: March 19, 2018, 06:59:54 AM »
Hi Guys,

This has probably been asked a million time so sorry for being such a noob!

I purchased my first all tube amplifier last year, the RT100H.

I've had a lot of fun with it so far and did the pre amp tube swap mentioned in other posts, (p2 & p5 including covered valve) or (p1 & p4 excluding covered valve)

Anyway, recently I'm getting a lot of loud microphonic noise in the clean channel, so I figure its time for a set of new valves rather than just one, as I bought the amp second hand and have no idea how old they all are. I am also not sure if I need to replace the input valve or just the 4 uncovered valves?

I'm really looking for reccomendations of that to replace them with. There are so many options available its all a little overhwleming to be honest! I have been looking on

Any help would be greatly appreciated!

Thanks in advance!
