I think most plastics have trouble with UV, and some fungi are pretty tough, anyway. The "idea" for me is to put the LP in a machine, turn it on, and return soon to a clean, dry LP that's ready to play on my turntable in my high-demands hi-fi system...

In our experiments, the more power we threw at the A7s, the better they worked. I heard some of the original "theater" version Altecs playing with their original "dedicated" Altec amps, and these sounded considerably better; but I never got ahol...

Hi Romy,
Thanks for the tip. I'll look into it. The highly recommended one over here is the Graham Slee Jazz Club. http://www.gspaudio.co.uk/preamps/jazzclub.htmHowever I want to try to get the old LEAK tube preamp to work first....

Adrian, Romy, (Dima), First, I most certainly agree that the textbook operating point for the 2A3 is not optimal and can be improved on, hence my own design from a few years ago. If you are sticking with a 2.5K load, you will simply not ge...

Again, none of the pneumatic methods would work as any pneumatic leak air with time and it will be no access to it after the horns are installed and the walls are finished. Not mention that we have no high to play wit. We will be doing the follo...

I agree the "period" closing needs more words, Roman.The P.A. horns/drivers were mounted in stadiums, convention centers, maxonic halls, cinemas, theaters, everywhere was needed a broad music or speech dispersion, trouble free operation and high S.P....

Romy,
Forgot to mention... The same people also offer a stepper-motor-actuated version, making it possible to do what you suggested above.
See it here (Scroll down to "Actuated Metering Valve") :

The surface of my fiberglass horns is quite rough. The mould was sprayed from a distance with some water based paint - so it all landed in fine globules. Maybe this is too fine a rough texture though. I like the idea of thick artists oil paint…

Paul, Some good valid points... yes, they've gotten much better over the years, no doubt to technology improvements. A good example is Mallory CGS caps made in the 80's versus new ones. The newer ones are much lighter physically (same p/n), hence th...

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…

Hi,
I am an analogue mania so naturally I love turntable.
I have acquired a Microseiki SX-8000 several month before and found it had speed irregularity. I thought first, the motor might be the problem but soon found there were scratch sound on the...

Well, from what you said,
if your TT has moods and sometime it works and sometime does not (the platter does
not lift up high enough) then the problem is most certainly is not a leak but
dirt and a lack of lubrication. You can test the lack of lub...

Kim, what I
would recommend if to keep presuming that the air pump do not supply enough air
