WAD 300b Custom Clone Power Amp, David Coe built at AD Audio
£2,000

Well this is a very, very reluctant sale indeed.
I bought this beautiful amp from the builder, renowned Valve amp engineer, David Coe from AD Audio.

He built the 300b for himself as the bench mark for all Valve amps going through his workshop.
So this was his personal amplifier.

When I purchased it, I intended it to see me to the grave... (I had badgered David for a long time to sell it to me) At the time I had some super lovely KUDOS speakers, and quite frankly it was end game.
Truly magical.

Alas, I then did a bloody ridiculous thing, like you do when you have the system sounding right!.....
Along came the Vintage Tannoy itch!!!
The 300b with my Tannoy Monitor Gold speakers has stunningly good Mids and the High frequencies, but sad to say with the Tannoy drivers, the bass was left a tad wanting. So I went out and got myself a Radford. Which, as widely documented on AoS was the perfect partner for the Tannoys.

So that brings me to this point with the WAD 300b custom clone.

This is a unique opportunity to take custody of an Amp Considered by many to be Among the world's best power amps, the WAD 300b has an enviable reputation and has that truly authentic 300b sound along with enough drive for a wide range of speakers.
This particular example was built as one of a very limited run of just four clones in custom made polished stainless steel chassis.

Point to Point all Silver wiring through out and Components used are of the highest available, Black Gate capacitors for the main power supply, cathode bypass and decoupling duties along with oil filled ASC capacitors and Mundorf Tube Caps. Resistors are Kiwame and Shinkoh.

The amp has been converted to battery bias (new self charging batteries just added) and has had the dissipation reduced to run TJ Meshplate valves.
It will come with a matched quad of wonderful TJ Meshplate valves.

Compared to the original circuit it also has additional chokes fitted to the input stage for greater dynamics and Image stability. The Sound is utterly exquisite and the amp produces around 25 watts with the TJ Meshplates.
The amp uses Zero negative feedback.
The amp also has transformer taps for 4,8, 16 ohms.

The amp is in Tip-Top condition, with only the odd faint swirl of a polish mark if you stare deep enough into the polished Stainless Steel finish. It has very recently been fully checked over and serviced by David Coe.

I can't stress enough how special this Amp is. It was a privilege to own such a thing.

It weighs an absolute Tonne and I will not sell without a demo.
So I'd really say collection only from Barnet.

It is offered exclusively here on AoS for a limited time.

I will add some further pictures, under the hood etc. later as i'm on my work computer and the pictures are else where.
