Peavey VTB 300 Tube Head

[bassdopp]

I'm looking to buy an old VTB 300 head. Is there anyone out there who might have a schematic or even a link to any tech info on this head. Thanks, John

Call Peavey, they will send schematics free, even for their old stuff.

Hartley Peavey designed that one himself. We have schematics. Contact customer service.

Thank you. I will contact customer service. I was afraid this was going to be too old for them. That's great news.

Bbby Bid, do you recall the output loads for the two 1/4" jacks for the speakers? It is not labeled on the back? I read a thread they are series, not parallel. John

That amp puts out 200 Watts RMS into 2 ohms, 150 into 4 ohms, and 100 into 8 ohms. Unlike other tube amps that have multiple taps on the output transformer, this amp only has 1 single tap, and the power is max when running into 2 ohms. The jacks are in parallel.

I've got one and it's ripped apart on my bench right now so I can rebuild it with a different preamp section.

I believe this is correct. I couldn't find my VTB schemo, but I did find the VTA400, which is similar, and that's how it's done.

Wow, that's the first I ever heard of a tube amp having reduced wattage with higher impedance...wild!

This is going to be a beast once again
