Dealing more with Sun Audio SV-2A3 kit it amassed me how bad the kit was. The guys made very cheap, in fact I hardly believe that this company has anything to do with Japan – it looks more like K-Mart level of amplifier. I heard a number of very positive comments about Sun Audio kits, well but who heard from me that the people in audio are mostly Morons…
Anyhow, I trashed everything that comes from Sun Audio besides the chassis, transformers and power resistors. I also got rid one gain stage on 6SN7. I have no idea what they make gain without power but it is another subject. To build the Sun Audio kit took 3 hours. To rebuild if in my way with my parts took 30 min. I was listing it and I did not really like what I heard. It is not that the parts were bad or wires were not “silver enough”. It was all together juts some kind of “Ordinary Sound”.
I was not pleased and I decided to go for what I know/ I got rid of the 6SN7 and put my 6E5P with cathode bias in the driver stage. I did not like the sound as well, in fact I like it even less then with 6SN7. Then I grounded the 6E5P and put it in more Milq-like configuration. I end up with 360V on B+, 15K plate load, grounded cathode, 160V on plate and -3.5V on grid via a series battery. It was slightly better but still I did not like 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 get from it is not right. So, I figured that it is most likely I have no speaker to use with this amp. The Tannoy Red are syrupy crap and I hear nothing with them. I need just another more or less full range speaker to evaluate the way how I might be used the DHT tube to drive my MF channel. I did not drive with the new 6E5P-2A3 Milq-Sun-Audio my MF channel as I would like to make the amps its good and then to apply the presumed success of my Sun-Audio amp to my MF channel with DSET-type transformers. (Most likely it will be inner-stage transformer)
So, with absent of the right speaker I will put the Milq-Sun-Audio journey on hold. This week my mashie pals me to fins the Mini-Me speaker and it might be good for get “clean sound” out of the Milq-Sun-Audio. So, will see how the Mini-Me will turn out.
Now about the contemporary production of 2A3 . Adrian, you proposed the KR tubes as good contemporary tubes:
There are also the Emission Labs:
and Sofia Electric
Did anyone have any experience with them?
