Thanks for that. I have gone through some repairs on the old ones I had which is a major pain. Chased after hum and whatnot. They are typically a little more than half the price of a new one though. Pros n cons n pros n cons :D I don't know, I really don't need one but man it sounded so good through my Berg 610.That was a heck of a rig. Can't I just be happy with a DB750?!? :laugh:

I think that if you can do the restoration work yourself, it's a lot more affordable. Tech fees can add up fast. At the same time, a new set of tubes, a power supply recap, and the replacement of some components can add up. Easy to spend the difference between the cost of the reissue and a good vintage one.

Some people prefer the vintage, others the reissue.

The only way that you'll really know is to spend some time with the reissue.

Sometimes you do. I held out for my 74 looking for one at the right price.

There are amps out there with a good service records. Repairs don't have to be worst case. Mine came with a good set of tubes. The caps needed replacing. But I can never leave well enough alone and can't resist changing things.

Yea, loved the 751 but the v4b was much sweeter for the gigs I do. With the V4b I can plug directly in and get a damn good gritty thump with little effort. I'm a minimalist I guess you could say.

I guess my only comment is that the DB is about as simple as it gets. This is kinda freaking me out though. :D o_O

I have received all of the parts I need to refurbish my VT-22 and convert it to to a head.

I'm hoping that one of you can snap a few pictures and take a few measurements of their head case next time you take out the chassis.

Specifically, I'm looking for dimensions on the grill and how it is mounted in place. Is the grill fastened with typical Ampeg grill snap fasteners or simply screwed in place?

I may as well build it as accurately as possible. In case some of these details vary by year, my amp was built in 77.

Thanks!

Have you checked out ampegv4.com ? They have a forum with a workshop sub-forum that can probably help you. If not, pm me and you can give me a call and we can do a video chat and get you the dimensions you need.

BTW - I love Fredericton. I was born down the road in Oromocto.

Thanks for the reply. I'll dig in the forums at AmpegV4.com and see what I can find.
Someone I know nearby has an old V4 as well. Maybe I can borrow it and examine it.

The dimensions of the cabinet from that era, front and back images, are in the TB portaflex wiki: 1970's Ampeg V4 Brochure.

My 74 has the front grille frame attached with screws. There are three blocks attached to the cabinet at the bottom and each side of the cabinet. You can see two of the blocks in the last image. Two screws with hex heads go through each block and into the grille frame. These heads did have differences. The back panel for the 70-74 is different from those of the later model. Here are two examples, the later model has white switches and the rectangular mesh.

BTW, fliptops.net sells repro cabinets.

Thank you very much. That's exactly what I wanted to see. Is that a piece of cork on the middle block? I may just omit that block... it doesn't look like it would accomplish anything.
Mine has the later style mesh back panel, but I can reuse the original one. It turns out that Ampeg just flipped them upside down on VT-22's. The small plaque will be upside down, but that doesn't bother me too much.

It is a small piece of cork attached to the front. The third block adds stability. The hole in the grille frame is large so I guess that the third block serves to strengthen it.

Here are some dimensions from my 74:

This is more thorough than I could have hoped for. Thank you very much.

I'll keep you all apprised of my progress.
