At the moment these are available as a package for £900 which is i think is a bargain.

1) Fully balanced satchmo valve preamp from David Coe at AD Audio.
2 x 6SL7 valves.
This one will come with -
Tung Sol 6SL7GT gold
Matched pair
10 hours usage
Purchased new from Hot Rox in 2020.
Single input and output.
Not many satchmo preamps about and i think this balanced version may be unique.

Highly thought of.

For clarity, this is not a buffer preamp, it is an active valve preamp.
David clears this up somewhere on his website.

2) El34 pp power amp.
Danbury transformers.
4 x JJ EL34L
2 x Toshiba 6AN8A

External valve power supply
Presume Danbury transformers.
2 x Brimar 5V4G

Comes with power leads.
some additional valves -
2 x Brimar 5V4G
2 x RCA 6AN8A

Sounds wonderful.
Gorgeous EL34 midrange.

The output transformers took a knock in transit, and are slightly unlevel, having slightly warped the rear of the top plate.
No affect to sound or performance, and noticable only from the rear.



It has been pointed out to me previously that a coupling cap has come loose at one end.
So i have been uising it with only 3 valves and never realised.
A slight imbalance in sound which i put down to one speakerbeign against a wall and another in fere speace.
It still sounded lovely.

A simple fix, but i don't drive and although i have had ofers to solder the looses coupling cap, it;s a busy time of year so have not go around to it as yet.

Collection from eton wick, near windsor.

A bargain £900 the pair.

These are up for sale because
1) the other half can't control her credit card spending
or
2) i got carried away again buying too much hifi.
I'm going with 1).
