  1. Think it's in the title? Excuse me if wrong but I suggest £1550 as a possibility, OP please advise? Also I have to say, a great line stage and great value at my guesstimated price, but really, a pic of a bag of stuff won't do! Perhaps better pics on the site rather than a link outside mate?

  2. Yeah, high current, no voltage, isn't that almost the definition of an effective earthing loop? Not my personal ambition to have one of those. Why do you want it guys? Sent from my BLA-L09 using Tapatalk
  3. Bad analogy. Try this: High current is like big thighs. If you want/find attractive the idea of a partner with big thighs then all power to you, go get. If you want big thighs for a reason outside material choice then the parameters for that choice may need to be understood. Maybe shot putting competitions, maybe Hill walking? Just not 'because'. Yes I can think of a few reasons why a s/s afficianado would want high current. But as a fan of easy loading speakers and small amps I am waiting to hear from you guys as to why?

  4. Hooray for Richer Sounds, Southampton, well done guys! Sent from my BLA-L09 using Tapatalk
  5. A quick couple of questions: What is the benefit of high current delivery in an amplifier, and why is this a desirable characteristic in my system? If we can answer one or both it is easier judge the merits of a given amp into given loudspeakers. Sent from my BLA-L09 using Tapatalk
  6. That's a lot of DAC for the money. Good luck Sir! If I didn't have 4.1x Sig I'd be all over this. Sent from my BLA-L09 using Tapatalk
  7. Looks like the VR is up and running so B+ appears OK. Heater circuit left to check... Sent from my BLA-L09 using Tapatalk
  8. Also, what amp is it, and who upgraded it, the manufacturer? Looks a bit like a Croft. Sent from my BLA-L09 using Tapatalk
  9. I wouldn't do that. I also wouldn't panic. No power to the filaments (ie. No glow) suggests a power supply issue. Unplug the mains, wait 5 minutes, then check if there are fuses in the amp. Report back... Sent from my BLA-L09 using Tapatalk
  10. You could do a lot worse than grabbing a cheap chip amp and seeing how you get on with that? Small, runs cool, clean, neutral, cheap. Seems to tick all the boxes (except cachet) Temple audio make posh ones, eBay has many many options for silly money. Sent from my BLA-L09 using Tapatalk
  11. It's worth first off swapping the valves for your others, just in case they've sub standard CH insulation, but really, you'll need to get it on a scope to trace where the hum is coming from. There's a lot of socking great transformers in quite close proximity to the signal valves, and the relay trafo right next to the '34s. It's a nice looking layout, but not a quiet looking one!

    SET amps

    Trouble with some of those old pentodes is the bases. Decent B5 bases are *very* thin on the ground, I know the Chinese make them but I'm not sure about their durability. It's a consideration if you are starting a project since, like locals, they can eat up a bit of budget and/or time locating them making the (happily cheaper) B5 based valves a less attractive proposition.

  13. With 105dB speakers you need a couple of watts or so, 6 max. In such amps hum is critical since most listening is with the amp delivering 1-20mW power, or up to a quarter of a volt at the speaker. It's not a valve thing, it's a circuit topology issue. If you have an amp that puts out 25W a channel then for most people that equates to 83-90dB 'average sensitivity' speakers and a few mV hum it will dissappear. At the sensitivity you have it will be a problem. So it's the amp. Get a smaller one with quieter PSU and enjoy your lovely speakers. Yamamoto or Tom Evans come to mind, or a nice T-amp?

  14. It's not unknown for manufacturers to mislabel valves, although Tfk wouldn't be an obvious candidate for this. I have a few, I find them interesting. They are plus or minus unused presumably because people bought them and then stick 'em in, they work badly, they pull 'em out, put them in a drawer, and stick another one in, job done. My money's on an ECC82, but as Richard says it could be an '83. Not enough experience of the '81 forms to have an opinion. It isn't AFAIK an '88, at least I've never seen a Tfk one with that construction. Sent from my BLA-L09 using Tapatalk

    valve problem?

    Never heard anyone moan on about microphonics EL34s or KT66s, they are octal based. Small signal valves need support internally to avoid microphony, power valves need support internally to avoid unwanted short circuits and similar. Yes it's part of the fun but one reason you will have to fight to find a microphonic Ecc88 type from any decent manufacturer is that they have a frame grid, bucket anode construction. The same cannot be said for 1940s 6SL7/6SN7 types. Any NOS there will almost without exception be rejects and measure/sound accordingly. For a really nice affordable 6SN7 try the RCA GTB variant. I'm not selling or hyping, merely advising, they are decent value. Sent from my BLA-L09 using Tapatalk
