I was playing lately with the Single-stage Melq and the DHT amp driving MF channel. It turned out that the Sun Audio VT-2A3 was very simple kit and it 2-3 hours to make it working. There is a lot in this kit that I do not like and some revisions will...

I kind of disagree with Adrian. The wire, the coupling caps, the cathode resistors and many other things are superbly important but it is after the strategic topology is settled. In my view caps, resistor, wire and other things are responsible for th...

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 posi...

[/quote] Funny it took 2.5 hours to build the San Audio Kit for 6E5P. The 6E5P is at 150V (a bit low for it but it is OK), loaded with 15K and coupled with 2A3 via a cap. The 6E5P is biased with one 3.6V lithium ba...

[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...

In context of the recent changes in my playback regarding the electricity and the consequential effects:

Possible, I never was a big fun of 6E5P without Milq type of bias. I remember what when I did the simple fixed bias when a few year back I was trying to make Milq to sound “contestable” with ML2 it was racy and jumpy sound but nothing special. I feel...

is what comes to mind when I reflect on your ponderings.There is a difference in "real knowing" in e.g. how to ride a bicycle (arse in the saddle), and then you can read a book about it, and then some more, and then write some PhD on the subject, yet...

[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...

You can gap it for 250mA or for 300mA – you still have some spare inductance. From what I see Pieter gave you a very good price for that chunk of core. If I decide to keep my “experimental” full-range SET amp (Sun Audio) then I will get from him a be...

Good summary, Markus, I would add a few more reasons but what is the point. The key is that bass from back loaded horns is dipole by nature or has a large dipole region. The back loaded horns produce bass similar in behavior of Sun during winter:...

[quote user="N-set"]BTW, how stable 6E5P is? I'm asking as I was contemplating biasing the output by the voltage drop on 6E5P's plate choke (DCR is say around 1k),with only some minimal autobias on the output. The drawback is that any drift in th...

I really enjoyed reading an ignorant rant by someone who has probably neither heard the Continuum turntable, nor who is willing to say anything substantive about its design, yet he's more than happy to mock me and the people who designed and built th...

When I meet Jonathan Valin I laugh. Jonathan is soft-spoken, kind-mannered person who does not have that revolting attitude of a typical audio reviewer. Most of audio reviewers that I met behaved like idiots, claiming: “the entire wo...

Funny, funny but those 2 47uf capacitors are the only eminent the worth to keep in this kit – they looks like very good polypropylene caps. I also a person who go uselessly go for chokes with high DCR not lover. Anyhow, I am not changing any magnetic...
