It looks like he stripped off the outer jacket and the end caps and removed the pole posts, so he now has the cap equivalent of a "naked resistor", like the parts geeks drool over.I dunno, but looking at the naked cap, I wonder how firmly and evenly ...

Does anyone know the voltage the big couping caps actually see? Yes, I should measure it, but I would rather avoid the drill of opening the amps, propping them up somehow and measuring if someone already knows the answer. Of course, I'm asking i...

[quote user="Romy the Cat"]A few post above Bill mentioned that he run his PP2000 from AdeptResponse power conditioner. I am not familiar if AdeptResponse helps to separate one PP2000 effect another. I am not also familiar with AdeptResponse its...

1) Be very careful with use Halco resistors. They were very good 15 years back but they turned south very aggressively. I bought a party of Halco in 2005 and I forced myself to trashed them as they were very noisy. You do not use then in critica...

...if you wish. even with Mex flavour ;-) I'm sorry I was imprecise. I ment exactly what you said...and forgout about 3200Hz...but I think that there is something more interesting going on here: what you have hereis rather a rare instance of an intel...

Decoud (and others), where do you source big Nichicon caps, pref. in EU?I'm slowly preparing to attack a Staxquiades - a mastodont Milq inspiredamp to power Stax headphones (PP 6E5 DC to PP 2A3/300B/EL34). I need 10.000uF/500V and 10.000/350V caps.Mo...

I have expressed this attitude before and I think it bites me by my tail again. Everyone tells that electrolytic in POS are bad. Well, I kind of follow this thinking as well but up to the point. The true is that I never was able to beat actively ...

After going through the anal pains of the Image Gallery upload (it is sohuge now that my browser slows down 10000x times loading it and it ocasionally kicksmy router out of this world; can we do something about it?), here are some picsof my assault o...

[quote user="Paul S"]Romy, isn't this the first time you have tried the film caps for PS and the "ALL-NEW" "SUPER-SOFT" diode bridge? I would certainly go back to known quantities before I did or un-did anything serious. Not that I always...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

I read it before but reading it now, after a few years again...

Finally looking under the hood, for the first time, my immediate observations are similar to those expressed by Romy and others who've checked and reported earlier: Top-Flight construction; "more than adequate" (but not "premium") parts. My amp...

I am not sure how much time I will have coming week to experiment with audio but if I do then here is what I would like mote have done. This week PurePower will return my second PP2000, presumably fixed. If this new unit sounds identical to my curre...

Hi Alex,I am sorry, what you claim can not be. No cap is going to separate bass instruments better.The brilliance of the 834p circuit is that the EQ also uses the miller capacitance of the tubes in a very brilliant way. The power supply caps are very...

[quote user="Bill"]You had that glorious sound with the 40 year old caps in the B2's and the Tannoy crossovers. Do you really want to move away from what they produced in your system. A good way of testing new vs. old caps would be to replace the tan...

Hi Romy,The builder insists that using five 400uF caps mounted in parallel to achieve the 2000uF required in that position should give some measurable benefits over using a single 2000uF cap. I really don't know if a single "big cap" c...

[quote user="N-set"]... I cannot imagine where the fuck I should have a loop??? [/quote] And you are not alone. Any single person who is chasing noise in phonostage ask himself the same question. I assure you that sun of later you will find it and it...

[quote user="Romy the Cat"]Brian, and how do you find your MOSFET behaves compare the 12AX7-based cathode follower?[/quote]Romy, I have yet to try. Only got them on recommendation very recently. They're cheap enough to try in a B9A plug-in without al...

Here is a good material with Chinese capacitor shootout
http://www.goodsoundclub.com/PDF/capacitorshootout.pdf
It looks like more or less intelligent writing, thought the caps sitting between stage and caps sitting in feedback work differently (con...

I was wondering how the record heat would affect your progress. Lucky you.Interesting observations about the air cap. Of course I am curious whether the added clarity additionally rewards/punishes +/- precision with VTA/SRA?I have zero ex...

CV, I am sorry for this mischievous teasing but at this point I would like to leave it as it: as the mischievous teasing. The entire project is not over yet: we still evaluating some optimum EQ aspects and screen supplies to make this phonostage bei...

Hmmm - the whole LCR thing, I don't like the idea. I'll admit to having no experience of it, but in engineering terms, it just gives you a constant impedance filter. The EQ is still done by caps essentially, far as I can tell. I see the wh...

[quote user="Romy the Cat"] [/quote]I really do not know what is going on and how to explain the phenomena; I just dump it to you “as is”. Because of multiple reasons I decided to drain the Milq’s power supply when the amp shits down. I have a...

Thanks Romy!I went with two tiers as I do not have much space between the speakers and the side walls as I have a 2.5M cabinet on the front wall.I named my amp Koshka as I always felt Koshka made a contribution to the development of the Melquiades an...

There are some very interesting moments with the not-so-expensive Sonicap Gen I caps, which I have described in the K&K thread. I will replace the 935s with these. I am willing to take the chance that the little .033 uF 1000V 950s in my unit...

Romy, I am aware of your well-reasoned prejudice against audiophile/boutique parts, and I agree that they are by-and-large the first recourse and last refuge of Morons.I thought I'd chronicled this phono stage stuff so far, but obviously not in ...

[quote user="cv"]I wonder if it is the reactive components (blocking caps etc) that are to blame here, seeing as much of the problem is in the lower bass.[/quote]Chris, what you said made me to think.
Look, the output of Bidat and a SS buffer that b...
