Sv20 head build

[audiosalvage]

Hello,  I'm settled on  building a sv20 which will be a clone on a lower power 1987x.  Unfortunately I would have to  fund it by selling my dsl20.  I like the dsl but it doesn't do what the sv20h  does.  I'm  having trouble convincing myself to go ahead and sell.  I have build about a dozen tube amps before but it's a bird in the hand

Did you ever start this?

If you're looking to build one, avoid the schematic drawn by Hugh Jorgan :)
It's got some major issues.
