Yeah--it was late when I first looked at the photo and I did a double take! Nice, big supply.

I've been somewhat lusting after something similar.

You can do some very good amp design experiments if that thing is up to operating standard.

Nice score!

Hey thanks.  Yeah, it is a little dead right now, I guess shipping causes the tubes to rattle loose.  But it looks like it should be easily repairable.  I bought it from a **very** reliable source, and he did say it was working well before shipping.

As for the Les Paul?  The guitar is actually a miniature.  The power supply is only 2" high, the LP 3" high... ::)

One of my best scores lately has been real substitution boxes.  They are heathkit, and the values have drifted a bit, but wow do those things make life **way** easier.  I cannot believe I have lived all these years without them.

So..... the picture

Never reach saturation, unless you want to.
