I don't mind talking about the "soul" of tubes. In my experience, the Kron 2A3 is vastly better Sovtek, etc., and better than NOS RCA 2A3 in my opinion. It has much more "soul" -- to the extent that listening became rather dull without it. I was shoc...

[quote user="Romy the Cat"]In meanwhile, if anyone has any proposal what tube to try in the Sun Audio audio kit’s output stage then let me know.[/quote]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rug...

The 6sn7 is a fine amplification tube for use in preamps or gain stages, but it has way too high of an output impedance for driving power tubes. This is my personal preference. It also depends greatly on the topology. Maybe George u...

… I do not consider it as an interesting driver and I have a good feeling that you will review your desire to drive 2A3 with 7788. 7788 is phenomenal for different application (ultra low noise + ultra high Mu) not for driving power triodes. Jim, if y...

My experience has been that tubes that run quiet and quiet down quickly and "properly" when tapped are almost always quiet with respect to self-noise and/or microphonics in use, apart from low level phono use. And most of my tubes tha...

[quote user="Romy the Cat"][quote user="drdna"] It has the Magnequest DS-025 OPT, connected to the 16 ohm tap. [/quote]
So, it is 2.5K primary and you drive 8R speaker with 16R tap. That makes the 2A3 loaded in your case with 1750R. I think it is ne...

I very slowly started to convert another amp to DHT. For now I listen just left channel and in a striped down mode: no tweeter and no Injection, letting the MF to care the whole upper range. It is interesting to play different tubes in this mode. Fra...

A most interesting post... and I can see how things get altered based on incremental changes to resolve one issue only to find another down the road, which is often disguised by components which simply don't perform in a pure manner. I've not heard ...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

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...

[quote user="Paul S"]Regarding your HF: Do you use a naked ribbon over 10k? If the PP2000 has worked for you, you might want to try it.[/quote]Well, I will try the PP2000 after I have finished evaluating the new 2A3 tubes. The EdgarHorn Titans use a...

Okay, I think I understand.... and thanks for the link on the YO-186... if I can ever locate some of these I'll be sure to grab some (hmmm, a trip to Russia perhaps). As tubes get very hot internally, there were some procedures for trying to eliminat...

Well, ultimately dropping the signal driving level to the 2A3 is the best approach for reasons already noted. If you can get a closer idea to how much you really need to drop, the simplest approach is having a custom IT wound with the correct r...

It is pretty much it. It is a fully functioning prototype built under the cover of the Milq top bulge. It has wiring for use both 2A3 or RE605/YO196 (not at the same time) and I think that the only thing is left it to power it from Milq and the see w...

I was searching for an answer why squire wave is so screwed and I was advised by the site’s visitors that it is due to HF restriction of my channel. My HF response does look too low to me – the 23kHz; with all my ultra low capacitance magnetic I ...

We all know how low-power SETs sound driving low-sensitively ported speakers. The Morons feel that it they have “enough volume” then their SET is good to go. Of course it is not the case and low-power SETs shell not driver dead speakers.
However, I ...

Hi Romy…and fellow audio nutters. I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner. My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I h...

Romy, the 6SN7 with 2A3, per se, even if slower than your 1-stage jobbies, should not be slow in the sense you describe, so something else must be up.If you get that far, you will eventually want "good" 6SN7s, for color and clarity (yes, they ca...

May ask you: how you drive your Reds 10” and the most important do you feel any their deficiency in power handling. I mean after the 109dB Macondo I have tendency to drive the small Reds slightly hard and this LF drive do...

[quote user="drdna"] If you were using, for example, the Kron KR 2A3, you would not be commenting on the sluggish liquid sounds, and it would be very much more competitive with the Melquiades I am sure of it. Adrian[/quote]I doubt swapping...

[quote user="Romy the Cat"]I was listing it and I did not really like what I heard. It was all together juts some kind of “Ordinary Sound”. I recognize that I say “I do not like sound” but I can’t say anything more spastic. All of the sound that I ge...

[quote user="floobydust"]As Romy pointed out, having high gain is not the same as power. If you're only barely cracking the volume control on your amplifier or preamplifier then it should be obvious that you have more gain than you need. If you're p...

Sure I was not able to do not listen it as the pain dried. It was incredible ad-hog sting of the drivers. All woofers are series. I know, I know but they are 4R each and I wanted to drive it with 2A3 just for the first test. The post is tuned - I hav...

I made experiments running HF filaments from dedicated Hammond 6.3V transformer vs. lifting ground on my 6.3V IDH filaments. I did not listen Sound but rather measure the noise – the result was identical. In the best cases I was able to get 0.63m...

I got my second version of new power amp up and running, this time using the 6E5P Romy recommended. Output tubes are 2A3. Amazingly, this amp runs at 0.12% distortion at 1W. No feedback anywhere. It is simple two stage amp run...

Romy, I tried out a 6e5p as a driver tube in a PP 2a3 amp (was using a 7788 for driver). Well, knock my socks off! The amp went from 6 watts to 8 watts! Distortion dropped a tad, but mostly it was more signal swing. I could dr...

Funny for in my DSET case it is mostly about a primitive equalization in MF. Well, almost.
I god a few other versions of 2A3, one more 604 and a few 45. I in fact like the 45s, even though with my attenuator wide open I have ~2dB less gain the...
