Older Ampeg USA SVT3PRO identification and value

[subrob]

Hello. Asking the forum's thoughts and experiences with the earlier SVT3PROs, please

Situation in brief is that a drummer friend has proposed a trade. My nice drum set, for his nice bass amp*. I have an idea of what my drum set is worth to me, but this, less so.

Scouring google, the modern faceplate model seems ubiquitous and this older model (which appears to be 2000 ish? USA made) is relatively rare. Does any citizen of this parish have any experience with the generational changes in the SVT3PRO? Any electronic or spec differences? Any specific things to look out for with these older models?

Also, while the pics are not the clearest, any help identifying the cab? Is it a HLF? It's certainly a 4x10, looks to be ported. As I say, my friend is a drummer by trade, so not ([s]bright[/s]) 100% conversant with the subtler differences. ;-)

Also, I've studied past sales on here and fleabay but this older model seems rare. Is that more or less valuable? Can I ask what sort of value others would place on these bits?

It's 3PRO from early 90's. There were not much different than modern ones, as far as I know they should be pretty much the same. Should be as reliable (or even more reliable due to no ROHS limitations!) as new ones. May need some pot cleaning or retube - but only if not working properly.
If you have no-name made in china tubes there, and the amp is working allright - leave them. They were very solid, mine had 11-years old 12au7 that was ~60% better than new Sovtek

The cab is SVT-410HLF or HLN (N were the same as F, but had Neutrik Speakons, later they got back to the HLF name).
