pre amp tubes for IIc+ (the bang for the buck way)

[cremona]

Hi

I think my preamp tubes are seeking there last days, the bass and dynamics seems to have faded and the amp sounds more birght and thrill.

Im on a bit of a budget , and i like to buy tubes that is also sold here in Denmark, thats means TAD,Tung-sol, JJ, ruby,Eletro harmonix,winged C, or mullard reisue.

I like to start out with 3/4 new tubes for the most critical possitions to see if that brings the amps mojo back , and then later on get some good Nos tubes.

Eny advice on tubes that fit the bill

Sovtek 12AX7WC is a very nice sounding inexpensive tube. Works well in any position. Also, I recently had a NOS JAN Phillips 5751 go microphonic during a gig. A bandmate lent me a Sovtek 12AXLPS to replace in V1 and I noticed *no* difference in tone or gain. A pleasant surprise!

For current production preamps in Mesas, I've always liked the Sovtek or EH variants...

When is the last time you replaced output tubes? This actually sounds more like symptoms of those failing...preamp tubes can last decades (not that they always will in a gigh gain amp, but....).

And if it is a preamp tube(s) it likely is not all of them that went bad. Hate to see you spend a lot of money on these and still have the problem (if it's output tubes).

Either way, good luck!

Hi guys

I had the power tubes replaced not long ago, maybe 2 month 2 tung sol 6l6 and 2 mulllard el 34 re isues , the amp sounded very similar to have it did before i change those so the are not the problem IMO.

I found 2 GE nos 12ax7 tubes in my simaul sat 85 amp and the had a huge differnce, espicialy in the P1 (phase inverter ).

so what would be the ideal tube for the phase inverter, my aim is as brutal as it can get :twisted:
