Need quick response !! Amp tech doesn't like V4 and reccomends ....

....getting rid of it. I just bought a V4 off Ebay and paid a premium becuase it came from a music store in Philly who claimed that everything checked out . Well it's making noise that sounds like a thunder storm that makes it unplayable. The music store wants me to ship it back; they have isolated the problem to the preamp.They want to repair it and ship it back to me.

The other option is to get my money back.

I called my local amp tech/guru and he tells me that he doesn't like V4's for a number of reasons. They are not point-to-point; they have printed circuit boards; the tube sockets are attached to the printed circuit boards(PCB) which heats up the PCBs causing them to warp and heating up all nearby components possibly causing problems.
He also says that these amps are not easy to work on and that his diagnosis and repair of my particular problem could cost me a few few hunded $s before he is through because it's very labor intensive. He said that he has worked on 3 V4s in the last month and recommends that I just get my money back and get a different amp(i.e. not a V4).

I really like the sound and reverb of the V4 but don't want to be plagued by problems. What opinions/advice can you give me ?

Regards,

Tom

Re: Need quick response !! Amp tech doesn't like V4 and reccomends ....

Hi,

I'll preface this by stating that I am NOT an amp tech, although I do manage to keep my own amps running.  That said, a well laid out pcb based amp can be just as good as a point-to-point or strip board based amp.  I've had my VT-22 for about 20 years and have only had to reflow one bad solder joint on the Ch.2 volume control and replace one capacitor.  (I still need to replace the power rocker switch.)  My amp has been gigged with extensively and there has been no board warpage or component damage from tube heat.  Sure, the V4/VT22 isn't that easy to work on as there are scores of parts that need to be removed in order to get at the chassis.  That alone can be a repair person's nightmare.  Of course, loads of amps are built like that.

Here's my 2 cents worth...  If the selling music store is willing to make the amp whole, with NO problems, and with NO additional cost to you other than $hipping (heavy buggers), then get the work done and keep it.

Of course, I got my first V4 amp in 1973, so I am VERY partial to them, as well as the VT22 combo that I own now.

Good luck.

Peace, Love, and Wah,
Geoffrey

Geoffrey,

Thank you. I am leaning the way that you have suggested. I'm going to try to get the music store to fix it and give me 90 days on the repair. If they can see their way through that then I'll keep it. I really like the sound of the amp; has more bottom end than my Fenders and I like the Reverb. My plan was to use this as my practice amp and my Ampeg Gemini 1 as my gigging amp(it would be mic'ed).

I also received an email from David R. and he has suggested that I keep it as well.Thank you both for the encouragement as I was considering doing this but wasn't 100% convinced; now I am.

Geoffrey,

As an aside, I just recieved my picture wah over the holidays and it is fantastic . I am running the picture wah on one board and my RMC-3 an the other. Have you evr set a tone with one wah and then run it through another?

Regards,

Tom

Hi Tom,

Interestingly, I also went to the V4 because it could give me my basic Fender sound that I'd used for years but more oomph.  I've never looked back.  However, I'm also a gear whore and have a nice stable of old (a.k.a. vintage) amps.

As for the wahs, yes, if you can think it, I've tried it.;-)  I still prefer one wah at a time, although numerous players now have more than one on their boards.

BTW - If you get the chance, ask your amp tech what type of rocker switch would be the proper replacement for a VT22/V4 master power on/off switch.  If he has one on hand, I'll buy it in a heartbeat.  Thanks.

Peace, Love, and Wah,
Geoffrey

Hi Tom,

WOW!  You've got a lot of stuff.  I guess that downgrades me from gear whore to a simple gear slut. ;-)

Thanks for trying to get the switch info.

Peace, Love, and Wah,
Geoffrey

Re: Need quick response !! Amp tech doesn't like V4 and reccomends ....

If you remember I scored a V4 on ebay that then gave me trouble so I sent it back to the music store to have it fixed. I got it back and it seemed to be working OK until last night at practice. The sound was cutting in and out and then it was distorting. At first I thought it must be a lose cable in my pedal board or the guitar cable. I've eliminated those two diagnosis and I may have to send it back for refund !!This is killing me because I love the sound .

Tom

I've definitely decided to send it back. If the music stores tech can't get it right then there is something seriously wrong here. Darn it ! May start looking for another; but I'll now be gun shy.

Re: Need quick response !! Amp tech doesn't like V4 and reccomends ....

His argument is faulty, as nearly all tube amps that your not going to shell out lots of cash for these days utilise PC Board construction. You generally will not have problems with an amp that mounts preamp tubes on PC Boards like Ampeg, Orange and a few other makes did in the 70's. --The PC boards that they utilised were solid enough.

The real problem arises whien you mount output tubes on PC boards due to their large size and the heat that they give off. Sterling Imports had this problem when they made Hiwatt amps. I've seen some Peavey's that utilised this construction technique, and I got rid of the nearly brand new Classic 50 I had for this very reason. As far as I know, Vintage Ampegs never employed this construction shortcut.

If possible, try to find another decent tech. Finding a good amp tech, though can be a bit problematic, as the ones who really know what they're doing and won't screw you over seem to be in the minorirty from what I've seen.

i'd say a tech that tells you to get your money back rather then try to screw you out of several hundard dollers for himself probably IS a good tech.  an honest one anyway.

Tube "gurus" have a tendency to be opinionated.   Regardless of his opinion,  the V-4 is a great amp.  My Vt-22 is my favorite high power guitar amp I've ever owned, and I've ownd quite a few.

The guy may be a good tech.  But there is no reason to stuff his opinions about circuit board construction down your throat.
a point to point handwired amp of this same power will cost almost twice what you probably paid for the V-4.

Geoffrey,

FWIW, if you can measure the physical dims of the current switch, a lot of times NTE electronics stuff will match up. I've used there switches on other Ampeg gear. Here's the link to their rockers:

Paul,

If you scroll down to a previous entry by Goeffrey Teese called "power rocker switches" or something like that he gives the source for a replacement.

Duly noted. Thanks, Tom. I keep a master list of sources for stuff like this. Knobs are the biggest PITA to match up.

Re: Need quick response !! Amp tech doesn't like V4 and reccomends ....

Paul,

Your welcome. Prior to Goeffrey finding that source there really was no other source for the switches. Even my amp tech couldn't find them. So this is a great find for all of us.
