I have far, far too many projects needing to find a good home. So I've decided to standardise on 3 designs to simplify building.

1. 26 preamp. This is a wonderful sounding DHT and very popular in the DIY community. A few Wammers have one already. 3 switchable inputs, Alps stepped attenuator. One chassis. Target price around £450. This could also be made as a 01A or 10Y preamp as required. 

2. 300b SE amp. Two chassis - power supply and main chassis. This will be 2 stages with a plate choke on the first stage. Best quality parts right through. Target price around £850 depending on OPT, e.g. one will be a Lundahl LL1664 and another a Hammond 1627SEA. Excludes 300b tubes. 

3. 2a3/6C4C SE amp. This will be 2 stages with a plate choke or resistor on the first stage. Best quality parts right through. One chassis. Target price around £650 with 6C4C output tubes. 

Anyone interested, send me a PM for more info and photos. Prices reduced for projects that need some finishing off. 

Location is Kensington Olympia, London W14

Photos to follow in this thread.

Hi Andy, some interesting kit there.

I think the MODs might be asking you for photos and location as per the AUP

I can't post a pic - not enough storage available. I'm looking at hosting sites to try and solve this. Any recommendations for a free photo hosting site? I'm a Mac user.

My 26 DHT preamp is for sale, now with upgraded power supply using polypropylene and DC Link capacitors. 

The modular chassis is the kind I use for prototyping, so more screw holes than usual.

If you can live with that, the internals are absolutely top quality right through

- teflon coupling caps

- Alps stepped attenuator

- Rod Coleman type regs on the 26 in filament bias

- 3 switchable RCA inputs.

I want to move this on, so price is £250, which is a bit of a bargain for a full featured 26 DHT preamp.
