    DC Offset different on both channels

    I haven't seen the circuit, but are there any trim pots? You may be able to dial it out.

    What's yer bits'n'bobs?

    I would still call that tidy!

    How do people have such neat and tidy systems? I have never managed it.

    Where is Serge .. I am losing my measurements

    Rather more than one, sadly.

    Where is Serge .. I am losing my measurements

    I eventually put him on my ignore list, not for his insistence that only measurements mattered, but for being insufferably rude to a new member who had at least as much experience as him, particularly in recording. Serge didn't like a dissenting voice from someone so knowledgeable, so resorted to arrogance. I also used to defer to him on measurements and technical questions, but not on the importance of them in subjective matters. In person I found him charming, but online? Not so much.

    What's yer bits'n'bobs?

    Continuing the loft system saga, unearthing, resurrecting, repairing and re-using stuff (Concordant pre, Ming Da EL84 power, Daphile music server on an old laptop, £5 DVD player for CDs, Heybrook HB3s via Spirit of the Wam, etc), I rooted out the old Sugden Connoisseur BD2 turntable that has laid dormant for 20 years, found an AT 10E cartridge and set them up. After sorting the short in the phono lead, and giving the motor a kick, I now have a working (ish) TT in the loft too. Nowhere to put it, and it jumps if I so much as breathe (springy loft floor), but still! I could find my old cassette deck, but I don't have any cassettes, so I won't. My wife has to phone me to get my attention now. I still have another three power amps, an analogue active crossover, Shackman electrostatic HF panels, SEAS tweeters, mids and bass drivers; I could go full active! Or get a life.

    SOLD: 45-0, 45-0 volt, 500VA toroidal transformer

    SOLD.
  11. I made a Lecson AP3 clone many years ago with this, but it had some hum, so I never used it. So the transformer is unused apart from testing. It includes the metal top plate and rubber pads. At the moment the equivalent is £82 from RS (inc free postage), so I am asking £30 plus £9 P&P. If you want to pick it up I am in Plymouth.

    And he hasn't changed, you'll be happy to hear. "I take things literally, so what does fun sound like and can you measure it?"

    If you are still missing him, he can be found here! https://www.audiosciencereview.com/forum/index.php?threads/measurements-of-parks-audio-puffin-phono-stage.5607/ I was curious about this digital phono stage, and voila!

    Do you still go to gigs or just purchase the music?

    It rains even more here in Plymouth! But it's warmer rain. Fallowfield for about 5 years, then Withington for the next 23 years.

    What's yer bits'n'bobs?

    I built this clone of a Concordant preamp about 30 years ago. It'a not the Excelsior, but a slightly earlier version, but then Doug Dunlop hardly built two the same! It has sat in the loft for about 20 years with no PSU, but as I was building a PSU for my 01A DHT pre, I thought I might as well make one for this. It's not valve regulated, but at least I used better heater regulators than the original, and made them parallel not series. It cost nothing but some time (and a big lump on my head where I banged it on a loft beam!), as I already had everything. But I will have to buy some better knobs; I only had chicken heads. The preamp case is brass, but instead of trying to polish it, I used some gold film I had left over from a sign writing job, and found some more for the PSU case. And you know what? It worked first time and actually sounds pretty good. It even has a decent phono stage. I'm running it into the little EL84 power amp and the Heybrook HB3s. I love it when a plan comes together.

    Resistor Testing Results - Anything to be Concerned About??

    Personally I wouldn't change the resistors if they are OK. It's far too easy to create problems where none exist at the moment, even the ones that are just out of tolerance. They are so close, that unless they are in an RIAA circuit I can't imagine they would cause any problems. But replacing them all might! Or maybe that's just me?

    Resistor Testing Results - Anything to be Concerned About??

    Is your component tester accurate enough to be certain of those results? IME, anything affordable isn't. But then, maybe you can afford more than I can?

    Getting active and never looking back

    Now that is the most interesting thing Keith has ever posted. IMO, obviously. Every speaker I have had (and I have built them all) sounded best with the tweeters above ear height. My theory is that it mimics live performances best, as the performers are generally above me. I don't sit in the gallery!

    Getting active and never looking back

    And in an analogue active crossover, the caps and resistors are much smaller, so cheaper for good quality items.

    Getting active and never looking back

    The only reason I am not active at the moment, is my wife's confusion with the system I had. Which was: source(s) - pre-amp - analogue active crossover - power amps - drivers in cabinets. To add a personal preference, it was EL84 PP amp to tweeters, 845 SE amp to mids (MF1000 has those now), Parasound HCA1205A 5 channel transistor amp to isobaric bass drivers. 4 channels used, one to each driver. YMMV.
