So I was playing my guitar today and my amps volume is maxing out at tv volume, its volume curve is normall till about 1.2 then it levels off and it doesn't go much higher. My amp is a Ampeg v50h and I had a set of groove tubes that came with the amp back in I think aprill of 2011. So GG&A do I need new tubesand if so which do you recommend?

Any other issues happening too? Like lack off bass, no "balls". Crackling sound. When my power tubes have gone bad, they've had all the above, doesn't mean they're the only symptoms though...as for replacements I love Groove tubes, otherwise JJs are really good too

^ All of that, plus personally power tubes dying on me have always had the symptoms of volume fluctuations. Sometimes it'll be quiet like you describe, then randomly jump to normal volume and back down.

I'm thinking its the electricity here too, there have been times when its deafining at zero. (the amp technically doesnt have a zero.

Sounds like power tubes, just like offworld said volume can really jump around if they're bad. I should mention you need to replace them with a matched set. Meaning you need to buy the power tubes in a "matched" set of 2 or 4.

yes. how old are they?

a significant volume drop is a huge factor. its also BAD to keep using the amp at this point. shut it down, refrian from using it until you have properly functioning tubes.

what amp is it? its always best practice to replace all the power tubes, get a matched set. if they sound good to you with no issues, try to buy the same brand and model and you can probably get away without a re-bias.

but its like changing a light bulb. it burns out. simple maintenance. if you own a tube amp, i think any guitarist can afford 30-60 or so bucks every year or so. sometimes you can easily span years.

The tubes are at least 3 year's old.

Groove Tube can mean anything, they rebrand all sorts of tubes. These days I'd say JJ are the go. If you want to know what was actually in it read me off the entire code on the tube.
Don't know how they are biased and I can't find a schematic. Find me a schematic and I'll tell you what it needs in that regard.

Sorry about the necrobump but I have an update and cathbard was right about the powertubes and now this thing roars. The amp had the orriginal powertubes in it so after 20 years I think it needed a change I got it done by a local shop for 40 bucks.
