Note: last evening I hooked up my meager rega planar 2 & radioshack 9v phono preamplifier for a listen. While I don't think the radio shack phono pre really provides quite enough output voltage to drive el cheapo, I was none the less thoroughly impressed w/ the combination.

Here's my setup

All built during the last 18 months.

6J5 preamp - centre

2A3 monoblocks - Left & right

Remote PSU - bottom centre

Home built tapered quarter wave tubes with Fostex FE108E Sigma full range drivers.

Bass is supported by MJ Acoustics Active Sub (with phone on top) at extreme right.

The 845 is being used to regulate the mains supply I suppose?

It's a trophy presented by the World Designs forum members at their show last June.

Doesn't do anything but it looks nice amongst the other glassware

No Bas it's a dead tube.

I won the trophy for progressing from valve audio newbie to having built a complete system in the space of one year using the advice of the forum members and my own reading of Morgan Jones.

Have a look here. This is my website which shows everything I built plus pictures from our forum meetings at the Eggborough Power Plant.
