Skushino, from what you say I presume you use two pair of ML2, right? Yes, what you say is correct but if I were you then I would not introduce an addition caps to signal path. In my view the best scenario for high path would be to minimize the coupl...

Yes, the last cap of power supply much be on the side of load as it shell have a short path to ground. Without it you will have “less bass”, more crosstalk in case it is a stereo amp with single PS and a few other negative things.
With cables is mor...

Wow, you sure do pack it in there! I like the way you silicone the caps and other things into place. Maybe you can do the same for the bleeder resistors and wiring bundles? That is, once you are sure it is operational. Wires c...

I was so glad to stumble on to this site. It's amazing!I've been a Bidat owner since 1995 and I had the latest mods done by John Wright a year ago. Romy, it takes several months for those blackgate caps to fully calm down, but you are in for a t...

Romy,
What specific objectives did the air caps address in the circuit? You refer to the tempted virtue sound but I am unsure as to the goals that you were trying to achieve with this circuit alteration?...

Actually those fantasies may come true one day...I may be wrong, but I thinkthe tube-speaker interface is more important than sticking to 2 stage topology?2 stage => high-mu output tube => high Rp, low controll over the array.But, if you insist...

What's the deal with all these expensive, small value caps? Are people paying this kind of money to bypass their cheaper couplers, or what?http://174.132.244.231/copper-teflon-capacitors.phpThis spiel contains a lot more "technical information" than...

Paul, I do not remember I had problems with 6AK5 sockets, and frankly I feel that your preoccupation with small socks of ML2 is a bit strange. If you “keep getting noise from the 12AX7/sockets, and this noise gets resolved when you clean the connect...

Like Romy said, the best route is something that's actually, practically useful and sustainable. I use Onix parts (also labeled NeoTech), and there is also FuruTech, and a couple of others. I think I gave you links to Chris VenHaus (US; he's also t...

Adrian, I specifically do not want to use wire to "compensate" for systemic problems. Like some pathetic believer, I have long held that the "best" wire would be "transparent". Since that appears increasingly unlikely, ...

I called to Audience and I spoke with their sales manager.
It was very little that I did not expect and I let him to run his sales pitch. Or course it never intended to be a commercial product, they did it for own home use but it was so good ...

How about lead acid batteries :-)Only half kidding - they would be cheaper than the caps and just think, you could finally ditch those AC power troubles away.Also the amps would adore the super low impedance power supply... Still, what with that enor...

First of all this post is NOT related to the recent PP2000 problems but it has a border, general view.
The recent LX’s posts made me to think about the PP2000 buttery. He reports that his buttery got way weaken from 2009. I used my older PP200...

Gregm,
I do not think that to be reasonable is a tall order, in fact I would insist that I nothing but reasonable.
Still, I feel that it is a huge distraction for people and a disappointment for me that others see juts an amplifier with a bi...

I'm wondering if Romy experimented with the feedback resistor quality. His ingenious contribution to the design was to use the purest caps possible as in the feedback loop every imperfection gets amplified. So the next logical step after caps wou...

That is a fancy one, with vacuum caps as I can see it. I do
not know about the practicality of vacuum caps – they have own pluses and minuses.
Still, that is nice crossover, a bit more complicated then I initially thought I
has to be. It would be ...

Hi,
Only noticed this now....

Then don't do it.

Correct.

A few days back I got rid of the 60-year old Germanium glass diodes in the REL detector and put in there the regular 1N4148 4pF low-signal diodes/ it was quite positive improvement. I need to be said that detector diodes are not the regulars diodes b...

How lucky I am! The Melquiades bass channel at full throttle gives me just enough gain to power my Midbass horn to the reference level of my MF channels. That is truly a very lucky thing. The biggest dilemma I am thinking now is type of the filt...

Adrian, I wrote extensively about the TAP in its own thread. Given good electricity, the pairing of K&K and TAP is a pretty clean gain path for the cartridge, with far more range, color, etc. - everything you'd want - in the end than the pr...

As I mentioned above, I talked to the manager of Fane International and asked for further assurances in writing that these new drivers would use exactly the same parts as the vintage drivers. I am quoting from the email, and I hope this will provide...

N-set, actually, I have seen a stacked-L schematic like you posted, with stacked caps layered over and R at earth for the tank, and I am on record as saying it is very elegant. So, sorry to be such a skeptic, but I learned a long time ago that the o...
