Chinese 12ax7b unmarked 8.99 tube is an awesome rock and roll tube, readily available at most tube websites. I have one in mine and its greatcharvelstrat81":2mcuduh1 said:What pre tube can i get for the 50 watters V1 socket that has more gain than the stock JJ?

yeah more really for the blue channel
Mine does not have all that much until i go to the red channel.
Yeppers. Understand. I use a boost on my 100 watt for the blue channel to get me where I want. Had a buddy who did the mod to his and he digs it. I just can't bring myself to do it so I boost it instead.charvelstrat81":1qb1tq4g said:victim5150":1qb1tq4g said:Good God man... More gain???

I modded mine to Stealth and it kills. I get the perfect amount of gain for my music on channel 2 dialed to 12:00. Theres some nice added girth to that channel now too.victim5150":2003f9ig said:Yeppers. Understand. I use a boost on my 100 watt for the blue channel to get me where I want.

Unlike the 100w, the 50w does not have a tube driven loop but is solid state.gtrplr71":1f3cui13 said:I was working on a commercial today and had 2 delays and 2 verbs in the loop noticed 5 volume drops, down and up I flipped it into standby flipped it back out of standby and it seems to be noisier than usual. I usually don't have to run my NS-2 but had to in order to finish. Turned the NS-2 off and it seems really noisy when I turn the effects loop on. Anybody had this issue? I looked at the 50 watt head tube diagram and cant determine witch tube is the effects loop tube.
Well I was on channel 3 when it happened. By the tube diagram it could be V1 thru V4. But Channel 3 now has feedback like crazy so it has to be a tube. Would a power tube do that or just preamp?nevusofota":dvi1vlxl said:Unlike the 100w, the 50w does not have a tube driven loop but is solid state.gtrplr71":dvi1vlxl said:I was working on a commercial today and had 2 delays and 2 verbs in the loop noticed 5 volume drops, down and up I flipped it into standby flipped it back out of standby and it seems to be noisier than usual.

Your problem does sound like a tube issue though.

It is more than likely V2 V3 or V4 because channel 1 and 2 have no real issues. I will try the tap test to see if 1 went microphonic. I guess I get a chance to see how my lucky Chinese 12ax7b's do in those slots. judging by most peoples comments it probably wont be a drastic difference. I would like a little less compression I feel there is a Mid compression that I a not digging to much, by that I mean more note clarity when playing chords.nevusofota":lecsi48t said:Preampgtrplr71":lecsi48t said:Well I was on channel 3 when it happened.

Found it V2! changing V2 to a Tong-Sol cleaned just a bit of lower mids up, So it does change the tone ever so slightly I suspect that changing all 3, V2, V3, V4 will probably make a bit of difference to my ears. Also the 12AX7's in there are unmarked.gtrplr71":3v07v5mx said:It is more than likely V2 V3 or V4 because channel 1 and 2 have no real issues. I will try the tap test to see if 1 went microphonic.

Thanks nevusofota I appreciate the help. I went ahead and retubed channel 3 all Tung-Sol and it made quite a bit of difference cleaner sounding for sure.nevusofota":28rn6eu8 said:Preampgtrplr71":28rn6eu8 said:Well I was on channel 3 when it happened.

did you ever find out what were the small issues that needed to be changed? i know there was the tracers that need to be snipped, a couple of jumpers, also a 22uf 35v cap on r37. r26 snipped, r25=10k, but h kaplan stated 'almost there but still a couple of small issues?'Padre Bonic":zsbhhkb4 said:I modded mine to Stealth and it kills.
