  1. That's a very nice 2a3 amp! Can you post the schematic?
  2. That's a similar theory to "you should always put your amps on top of your speakers - that way the electrons find it easier to drop down into the voice coils"
  3. I think "Dunker Factor" is worth mention. " In the early to mid 1990s the Norwegian "boat anchor" valve amplifier constructor Thomas Dunker published some groundbreaking essays on how to replace the famous unsinkable "Norwegian Wood" with left over NATO boat anchors, or failing that by massive valve amps. A measuring unit, the Infamous Dunker Factor was named after him by fellow audiophiles. The Dunker Factor defines the sink rate (m/sec) proportional to the amplifiers weight/output ratio (t/mW). So a Dunker Factor of 1 says that 1 amp of 1000kg and 1000 mW will sink at 1 meter/second. Following his example, constructors of valve amps strive for a Dunker factor of 1. This can be achieved with an amplifier of 1,000kg which can produce 1 Watt into their speakers."
  4. I'm the one that's Welsh! From Bridgend, Glam. There you are, then.
  5. I bet you have an amp that goes up to 11 and enjoy playing in D minor, the saddest of all keys.....
  6. Another experience comes to mind from the 1970s. Me and the drummer in our band were looking for a cheap stage amp, and so we went into the local junk shop (yes, these used to exist) to have a look at what they had. The guy at the counter had a rummage round and with a wide smile hauled a scruffy old amp onto the counter for us to have a look. Conversation went... Guy: "You'll like this one boys. It's a goodun." Us: "So how much power does it have?" Guy: "Ah, you'll be fine with this one, boys. Says on the back it gives out a full 8 ohms!"
  7. If you're free on Sunday we could have a dribbling contest and read Jabberwocky.....
  8. Hopefully we can have some fun with this thread! Delusional is a word commonly associated with cables and oak feet, but it goes much further than that. So can you think of any mind twisting exeriences in your audio history? My contribution is that after days of doing calculations for a new amplifier circuit, I wake up in the night trying to apply Ohms Law to sleep. I try to determine how many hours I need to sleep in relation to the current involved in the sleeping process....... Yes, doctor, I'll come quietly.
  9. Drastic price reduction to £570. This is as low as I can go. Advertised elsewhere.
  10. Ahhhh..... vintage. Wonderful. In my case tubes from the 1920s and 1930s before the Americans came along and standardised on 9 pin and octal sockets and 6.3v filaments. I love all the old European sockets and all the old 4v and 13v radio tubes, and I have quite a collection of them. All the rest of the components are pretty fresh - not into old capacitors and resistors!!!
  11. I think that's an unnecessary demand. I've regularly used 89db down to 86db speakers at lower volumes in a medium/small room without issues, and bass hasn't been a problem. I'm not quite clear about what your priorities are as a listener, since you remain unsatisfied. Mine are transparency and timbre, and of course the timbre on voices and acoustic instruments is generally accepted as anywhere between very good and magical with well designed 300b SEs.
  12. I was lucky enough to hear a Lamm 6C33C SE amp at one of the shows. It was wonderful. That's a clever design from a guy who understood Russian tubes. From what I understand, though, quality control on the 6C33C was pretty variable - they measured all over the place. As with a lot of Russian tubes, a lot were made for the military and they turn up anywhere these days, including presumably some non-premium ones. Mind, quality control on most Russian tubes was pretty good.
  13. That's not what I'm getting from my 300b SE amps. Nothing slow and soggy - on the contrary, my amps are exceptionally clean and clear, but I've been optimising the designs for 12 years. No "slow and soggy" input tubes here like 12AX7 etc. and the input tube matters hugely. Yes, of course, if you want power and current look elsewhere - no disagreement there. But a lot of audiophiles listen at lower volumes in smaller rooms. And frequency response shouldn't really be a big issue. If it were there would be a lot less 300b amps around than there actually are.
  14. Try it? Should work.
  15. Why? I've found 300b SE amps very easy on speakers - most of them sound good to me, including bookshelf speakers.
