First, Adrian, Thanks for your feedback on the newer designed 2A3 tubes... very interesting. I've looked at all 3 of these brands before but have not as of yet purchased any (I have a large collection of 45 and 2A3 of various NOS US brands...

Please, guys, I'm not an experienced builder at all!!Please don't offed a real experienced builders! I'm rather both hopelessly stupidand ignorant. Knowing that, I'm trying to be carefull. That's all. My active participation here, apart from the spir...

Romy,Try wrapping a copper wire around a power cable, then "inject" it into the power line through an isolation transformer. The wrapping only to help defeat the antenna event of other signal sources that only have one vector.et all,For cables, the m...

[quote user="decoud"]Romy, I imagine it is irrelevant but have you found a difference between lower and higher voltage versions of the Electocube 950 series in the coupling capacitor position in the full range Melq? I ask because a stock of 1000V has...

[quote user="Lbjefferies7"]I would be most interested in that description of that specific sound. [/quote]Well I do understand that with 6.3’ piano I will not get the “crash” of the 9.8’ Bosendorfer but “full bass” is not only what I am looking. I a...

I would like to point out to a very important moment that took place in here. I do presume that Jessie account is very accurate and the Teflon sockets were bad. I even presume that they were bad not only from the perspective of cooling but were bad s...

Hi to everybody,I have used those caps: teflon V-caps, AN copper, Jensen copper, Siemens at the signal path of a tube power amplifier (300b SE) application. V-caps are technically very good, very clear, less microphonics, but missing s...

Functionally, these are the same caps I already replaced once/twice (and wrote about) before, namely the big "parafeed" couplers. The unit came with bypassed 4 uF Kimbers, which were fuzzy and slow, so I replaced them with 3.3 uF Mundorf Silver...

Paul, in my view the air-caps as an ultimate cap, the ultimate by own intrinsic topology. It is particularly the case for the 834P- like application as in there the cap is not biased by high voltage DC and gets constantly re-polarized. You see the pr...

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...

It does not sound right to me. If I am not mistaken then it has 2 X2uF caps. What 10uF coupling cap can do there and what 1000V cap does in ML2. The 1000V cap is almost $6 more expensive – Lamm would kill himself but would never allow such a waste of...

Romy,
I'm sorry the output tube dampers didn't work out for you. Maybe you already had the microphonics/mechanical grounding so well taken care of that there was no benefit. I had observed a significant effect in 2 different installations out her...

Remember the death and "re-birth" (via good electricity) of the big Cardas caps? Well, it finally got to where things were not made good enough anymore by good electricity, so I went on the hunt again. This time I settled on Sonicaps from Sonic Cra...

[quote user="Paul S"]But why would you consider brass connectors because of 95% of boutique RCA if the idea is to wind up with the best signal path?[/quote]Of course not because of that! The ideal would be the connector I've shown but made with pure ...

[quote user="Patrick Mattucci"] Some say that we have better materials used in bearings and tonearms and cantilevers. We have better stylii today than we did in the 70's and 80's. When it comes to cartridges, I'm about 90% in agreement that today's a...

[quote user="Romy the Cat"]So, Teflon, I do not think you got what I meant. SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demand...

This weekend I will be finishing the whole Milq modefication, putting it back to the full-time service and this Sunday the James Levine’s live-to-tape broadcast of “Simon Boccanegra” is was planning to listen via the reincarnated Macondo.

Doug, it is a lot of tuner went over your hand. I wonder what drove you to do so. Was any specific quality of sound that you were looking and the tuner that you own did not serve you?

A small word of advice regarding wiring the 6c33c heaters.My DSET's have now have several thousand hours of use and I love them to death. I've not heard any amplifier able to do what they do. The first amp has over 10,000 hours now and has never fa...

Referring to the threads a few month back:

I wonder if I need to play with the coupling cap between the first and second stage. Now I have my beloved ElectrocuCube 950. In my former version...

This has been one hell of a ride! The new caps had gotten so bad yesterday and this morning that I was almost convinced (again...) that my cartridge was finally, really shot this time; what else could it be? The upper mids and lower treble had suck...

Thanks, JJ.
I do not necessary feel that it should be any difference between the early Hal-O production and the new version – they are essentially are the same products with different descriptions. For new dampers should be better only for lar...

Paul,
I've see the post you referenced today, and I am still thinking about cable construction:

I would like to pass my observation about the whole notion of
Goto vs S2. Some might feel that that my observations would be less relevant as
I personally did not experiment with Goto drivers. So, there is no reason for
you to read further. I head...
