I've got a Musicman RD-100 head that I bought s/h about 20 years ago and as far as I can remember, I've never replaced the tubes in it. I started using it again recently and thought it might benefit from new tubes as it doesn't sound as good as it used to, especially when the bright switch is on. There are two valves that I can see in there (the amp has transistor stages too) one EL34G and one 6CA7, I've seen a few places that sell EL34's but not EL34G's, does this matter? 6CA7's seem to be fairly easily available though. I've also seen pairs of valves for sale as follows, would these do the job?
