The VOX AC15H1TV I got had to go back because all the tubes were microphonic and were tinkering right through the speaker.
If the one I get to replace it also has issues, I'm giving up on the amp.
Soundwise, it was pretty damn awesome, but I can't afford to buy a new amp that has crapped out so soon.
All the tubes? You mean all the pre-amp tubes? According to what?
Some one needs to give you a crash course in basic amp maintenance. Swapping V1 and V2 would likely have cured the issues, and taken a lot less time then packing it back up.
When you tap a tube lightly with a pencil eraser, and you hear DOING sounds coming out of your speaker, there's a damn good chance your preamp tubes are microphonic. I checked every tube in every position, with very light taps, and clangy sounds were loud and clear coming through the amplifier. This doesn't happen with any other tube amplifier I've owned, and it's obvious that it's a pretty big issue, especially in a combo amplifier. The tube sockets aren't too sturdy either. For a brand new amp, this isn't something I should have to worry about.
I've owned about 13 tube amps in my life, and currently own seven. I have never gotten a new amp with more than one bad tube. I've never had an amp that I had to replace every tube out of the damn box, and I shouldn't have to drop $100 minimum on new glass the second I get an amplifier. Especially when I'm paying $1000 dollars for it.
Second off, if you knew anything about the amp, you would know that V1 is an EF86 tube, and I hate to tell you, but very few people have a box of EF86 tubes stashed in a drawer in their house, Mr. Deganaro. The fact that the EF86 is very prone to microphonics doesn't help either, AND the fact that I checked both the EF86 channel, AND the top boost channel, which does NOT use the EF86 tube, and still had issues.
I asked for replacement tubes from my dealer, and they said that they don't even stock the tube, and they would like me to send back the amplifier.
I got the second one today, and it has the same issues. I'm done playing musical amps with Vox.
