  1. https://postimg.cc/KKtK6BpL Should give you a pic of the 26 Preamp .
  2. 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.
  3. One 26 DHT preamp presently for sale. - 3 inputs switchable - Alps stepped attenuator - Rod Coleman type regs in filament bias, no bypass caps - Teflon coupling caps - Gain around x8 £325. Collection from Kensington. Try for a week and return option. Photo available by PM, or email me directly as above in thread. Best, Andy

  5. Very nice piece. Plenty of room for mods. You could even put a DAC board in there and convert it into a DAC-Pre. That would be even nicer. Plenty of Chinese DAC boards on eBay. I use a AK4490 which is back a generation or two but still sounds very nice.
  6. I do indeed have a couple of 26 preamps for sale. A single chassis 26 preamp is £385. I have a more elaborate one as well with separate filament supply.
  7. Valve amps can last forever with point to point wiring. Just upgrade any parts that need it. But for something without high voltages (apart from the mains) have a look at a really good DIY amp. If you can make it you can repair it. A very popular example is the Nelson Pass Amp Camp available from the DIY Audio shop: https://diyaudiostore.com/products/amp-camp-amp-kit?variant=7072933085218 This is class A Single Ended so expect some good sounds. You can see some built examples sometimes: https://www.ebay.co.uk/itm/114869050075?hash=item1abeba9adb:g:wKwAAOSw0h1g2L~n However, in this comparison a simple tube amp did well.
  8. You can get me at performanceandmedia. That's at g-mail (com)
  9. Thanks for that. I've added the location and I will post some photos ASAP
  10. 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. Andy
  11. Buzzing transformer never stopped buzzing - have another identical which also buzzes! I'll probably use them for preamps with low current and mount them on something non-resonant. Anyway.....

  12. Just to fill you in here, Duncanamps has an excellent database which is really helpful and contains a vast number of available tubes with their data. It's a good resource like Franks Tubes. What I posted is a list of the most consulted pages on the site, which shows what users of tube equipment are looking up on the site. All the other tubes are on the site, but are consulted less often which suggests they are used less. The most consulted tube types also happen to be exactly those that occur most often in online schematics and commercial tube amps and preamps. And stage amps and studio equipment of course.
  13. It's very US-centric like a lot of audio sites. And the common tubes are all US tubes introduced after WWII with the revised octal and 9 pin bases. I've been having a lot of fun, and some very good results, from European tubes previous to WWII.
