Haralanov,
I spoke with a guy who consulted me during my Electo-Vitavox project. He helped me with selection of core material, deliberated the core and calculated the right coil to keep the core mass optimally magnetized. He has over 40 experi...

I think it is quite helpful to have some information about VTA in general.In the 50's there was no cutting standard, that means, every Label did cut their records the way they wanted ( the angle for Mercury, RCA LS, Decca etc. are all different). At ...

Both speakers have the 78 hz. Dip after a 50 hz. Peak. they are probably room resonances. Try moving the speakers and/ or the mike and remeasure.Also you have the sa...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...

Romy,
Thanks for the advice.
Just to be clear here :
When you say
"Short the ML2’s inputs and the hiss should be gone"
I assume it is not a mistake, and that you mean short the unused input on each POWER AMP (as opposed to the PREAMP...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

[quote user="guy sergeant"]When I worked for a UK based tube amp manufacturer some 10 years ago we had a couple of pre-amps using OA2's in shunt regulator circuits. These (physically shorter than standard) OA2's came from Richardson and did work very...

I discovered a station I really like, with a good percentage of "content-loaded" music, and in any case, a playlist FULL of surprises :

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

Hello, would it be possible for us to see the diagrams and schematics behind the Zarathustra II in the same spirit as the Melquiades was conceived, noting that the best of ideas are formed with the purest of sentiments?[quote]It is Dima’s and my stro...

Thanks, floobydust.
There are a lot of interesting points in you post to consider. What speaker you drive with your 2A3? If they are relatively high sensitively (like compression drivers) then did you consider going with a single stage? I think I ha...

[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...

Romy and Paul,
Thanks to both of you for the further input.

If I do as suggested, and this removes the hiss, that's great; only one problem (forgive my slowness in understanding here); with the plugs in place, how do I then get a sign...

Well, in context of a full-range speaker, like largest Wilsons or the similar, the answer would be unquestionably no. Even if we biamp those speakers then the LF still is too wide bandwidth and too geographically bind to the MF section. The wor...

Paul,
The idea of the not threaded forum is good that it is always there is opportunity to go back to all there and update own views, or to extend them. In many moths/years when the ML2 stop be a novelty for you, you might return to this thered and ...

[quote user="floobydust"]The 2A3 can be almost as quiet, but ONLY in the dual-section paralleled types. I adopted a split balance technique. It only works with cathode bias due to the topology but it is effective. You also need a good quality filamen...
