cool old ampeg, never seen one of these before

I've never seen one of those, but what a cool amp. Big transformers and 4 6550s - it should have a little more grunt than a stock V4B. Nothing wrong with that.

 

Here's a few other SVT-100 threads and posts for anyone interested:

I've got a V5 guitar head that looks almost identical to that. I believe they are MTT and were made in Japan. I run it through a V4 4x12 and Fender BXR115. Not quite as smooth the 300w SVT because I have to drive it a little harder, but has a real nice old school sound.

 

The SVT-100s were some of the first amps that were made right after SLM acquired Ampeg in 1986. As a matter of fact, there were only three models of amps offered in 1986; the SVT, SVT-100 and B-15. They were originally lead guitar amps, but they sounded terrible for guitar so they were turned into bass amps and they only made 100 the first year. It's a nice piece of Ampeg history.

 

If you read on these were US designed and made in Japan.

 

The SVT-100's were MTI era V-5 guitar amps.
