  1. might have been more interesting if the writers had started by looking at what had been on "Later..._with_Jools_Holland" throughout the decade. Some really good tunes and artists Later... with Jools Holland - Wikipedia, the free encyclopedia
  2. It's bizarre there is no mention of the Sugababes, first hit in 2001, 25 singles since then, 17 in the UK top 10 and still going. KT Tunstall is one artist I really like.
  3. It has come with a new pair of Amperex 7062 PQ and is sounding very good I`ve got a pair of pinched waist 7062 coming for christmas
  4. according to amb a 100K+ resistive impedance is "super easy" for my beta22 to drive. The capacitive load however may require an output inductor on each channel in order to stabilize the amp. I will only ever be driving this application balanced. p.s. been a while since I was called a chap
  5. the figures I am working with are mini-dac output (+4dBu) = 1.228V beta22 gain = 1:2 so max voltage output = 2.455V Stax transformer gain = 1:25 Voltage on the transformer secondaries = 25 * 2.455V = 61.38V or +38dBu
  6. I won`t need an audio transformer for my board (if my calculations are right). I am looking for inbuilt non-resistive attenuation of around -40dBu. A 1:25 transformer gives +38dBu when fed +4dBu from my mini-dac via my amp with its gain of two. Missing out these transformers (provided my beta22 remains stable with the capacitive load and is happy with the resistive load) will achieve in one stroke a real 38dBu cut to final listening volume and should accomplish what is a main aim of this project for me.
  7. I went with a wool knop filled pillow as when I tried a memory foam one, I found it too firm, overly warm and the smell was too strong (but I`m sensitive in that regard, ymmv).
  8. so suggestions for tubes for an Exemplar Audio modified Denon 2900 ?
  9. good to know, must have been an error on the sellers part.
  10. p.s. The first amp this will feed is my ckkIII (with donuts), once the beta22 reappears, the beta22 will probably be my main amp.
  11. It may possibly come to pass that I could soon be the owner of an EA Denon 9200. It will come with one EL34 tube, so I'll need to get a matched pair of tubes and fit them before I will hear it. A matched pair of Electro Harmonix EL34 will set me back
  12. without presenting the amp with such a high impedance load.
  13. what is the usual step-up ratio of the transformers and what impedance do they usually present to the amp driving them? I`m wondering if it might be possible to use transformers with a gain 100 times lower and therefor achieve -40dBu. p.s. thankyou for all this help
  14. does what you said above also apply to the large SRD-7 ? if recasing is going to be necessary are there any advantages in getting an SRD-* box, apart from a source for stax sockets ?
  15. great so SRD-* box, bias supply with Hammond 229A230, 10M ohm pot, VC99 voltmeter. anything else I should look ?
  16. got a reply, it is linear and is he thinks rated for 500v.
  17. VC99 it is then And for the pot would this do ? Panel Bushing Mount - Pots with Shaft, Single Turn - 500k Ohm & Up (RCV) JJP97662
  18. VC99 is easy for me to get over here (via eBay) if an inbuilt voltmeter isn't feasible. Is there a pot you have in mind for the shunt pot ?
  19. that was me, that was, I even sent them to APS for recabling - polishing a turd now I`m far happier with the donuts and rs-1
