MANY WILL REMEMBER THIS AMP AND ITS TRIALS AND TRIBULATIONS.- IT IS NOW ABOUT TO BE AUCTIONED OFF AS PER THE INSTRUCTIONS OF THE OWNER AND PROCEEDS GOING TO CHARITY. ALL MEMBERS REGISTERED AT TIME OF THIS BEING POSTED ARE ALLOWED TO BID, ALTHOUGH YOU WILL REQUIRE TO BE RESIDENT IN UK OR HAVE A UK BANK AND BE ABLE TO PICK UP.... OR HAVE AGENTS WHO CAN DO SO.
(any questions can be sent to me or another member of the mod team)
THIS IS A UK ONLY AUCTION FOR OBVIOUS REASONS AND PAYMENTS ARE BY CASH ON PICKUP, PAYPAL GIFT OR BANK TRANSFER (probably) YOU WILL HAVE TO COLLECT WITHIN 4 WEEKS AFTER PAYING BY PAYPAL ETC OR 1 WEEK IF BY CASH.
This valve amp is a true hard wired amp and uses high quality components. It was checked over and repaired by our own Anthony TD and has been classed as in excellent health and sounding very good. This amp is very heavy so will need to be picked up from his house as suitable packaging is not available. doubt a normal courier would do it anyways or insure it due to weight etc.
This would be a great xmas pressie for someone, and anyone wanting to buy it for me I will be very grateful:eyebrows:

The amp uses 2 x ECC82/12AU7 in the first stages, 2x 6SN7 in the second, and driver stage, And 4 x KT88 in the output stage. The output stage is grid biased, with individual bias setting controls on each output valve.
The amp also has adjustment for balancing the driver circuits, which offers the advantage of being able to adjust the signal being fed to each output valve quite accurately , which in turn helps in reducing the over-all distortion.
The gain stage valves all have DC supplied heaters to ensure low noise. It also has dual mono HT supplies, [shared mains transformer windings] with a decent pair of Chokes situated inside the chassis.
There is 4*6550's currently fitted, it has to be stressed that when it comes to changing the output valves in it, each valve has to be individually biased using the controls inside, if the winning bidder is not technically experienced enough to do this, then when a revalve is necessary, it will need to be taken to someone who is technically qualified to carry it out.
(Anthony on the amps running):
"There is currently no objectionable hum,in fact, it is very quiet, even on my bench' which usually amplifies mechanical hum due to it being hollow beneath!
As to the original fault, i am now quite sure that the issues experienced by the OP where genuine, but were down not to any design, or build issue, but output valve failure, possibly due to transit damage or, possibly due to this particular set of output valves not being able to withstand the high'ish HT voltages etc.
The more i look at this amp, the harder it is [for me] to understand how the guy made any money from making it! Having been involved in this industry for over 20 years now, i am fully aware of how much time and effort it takes to build something like this, also' the costs involved in sourcing all the parts etc."
Bids to start at £250, which I sincerely hope is blown away by a huge amount. This, although not the prettiest amp in the world is superbly made with quality parts. It really needs 2 to lift this, if you dont want a hernia as its very heavy (not weighed but thought to be about 30/35 kgs). Location is in S Wales, but Anthony is kindly prepared to meet along the M4 corridor somewhere(think that goes to London) which may help a lot of folk
Anyone who is prepared to assist in this good cause that travels to and from S Wales could offer ther services as a taxi:eyebrows:
SEND BIDS TO ME BY PM AND I WILL THEN PLACE THEM IN THE AD, EITHER WITH YOUR NAME OR IF YOU WISH, ANONYMOUSLY.
THE CHARITY TO BENEFIT IS CANCER RESEARCH UK.
HAPPY BIDDING, AND FINAL BIDS WILL BE ON THE 20TH AT 20.00HRS
