Hi there,

better than my previous SE 300B, above all in bass region !

The latest integrated amp...

I'm just waiting for the nixie in the mail to plug that hole :)

It has phono plus 3 inputs, a 10Hz 4th order HF filter, 6E2 meters, an OTL headphone amp good down to 32R that doubles as the line stage, and a triode strapped output stage good for about 50W.

Power supply is in a separate chassis (obviously).

I decidedly like the aerial shot :)

The hardest thing about building this entire thing was soldering the shield wire on that damned RG6! (No I wouldn't have used it if I had ANYTHING thinner at all). I had to use my old school quartz 60W pencil iron. I must build a spot welder :)

Wow - that is amazing!! 27 valves! How many watts go to the heaters?
 
...new amp :p... four CV4043 (6BW6) per channel, ECF80 in drive/phase splitter... Lundahls output... wanted to try the wood/epoxy combo, looks a bit turtle-ish but I like it... runs pretty hot though.... me happy :p
