There seems to be several lower cost Asian made CD players that have a tube output and also HDCD support. I could use a power transformer to match the...
... Thanks, I had spotted the Mini Max already but I can't find this 10 year anniversay edition you mention. The "regular" CD120 doesn't support HDCD. If you...
Paba: Shanling is not bad. I do not like the others much. I think an old PS Audio Ultralink II (not tube) with HDCD will perform a lot better. If you muct...
hi Dr John, I bought a nice Made in China 2A3C SE amp. The amp is ok sounding but need tuning a bit as there is no much mid and low.... After tuning the...
Hi doctorjohn Yes, Tanuski has done a great job. This Sunaudio amp looks good but the arrangement seems to be pretty complicated with 3 stages and an IT. I am...

_____________________________________ Dear Sir (LKT of Camera22), Thanks for your e-mail. The Sun Audio 300BTE delivers 8 solid watts. And the sound is quite ...
Hi, ... I think if had measured the poweroutput you would found it closer to 4-5W. You may also consult the WE datasheets, for 270V/50mA/3K5 load you will find...
Hi Thorsten ... the 300B at 350V/60mA/3K5 which gives around 6....7Watt output (realistically) and also apply fixed bias in the driver stage Can you please...
Hi Thorsten Thanks for the info and links. With the 417a/it/300b circuit, should a grid choke be used instead of the 100k resistor that goes before the 417a?...
Hi, ... of ... Not necessarily. But it can be used. ... Again, this depends. As it stands, the 417A will have a gain of around 40 with the 300B having a bias...
Hi, ... While there, see if you can get a pair of his silver/mica 0.1uF Capacitors. Connect from 417A Anode to 300B grid, effectively bridging the interstage ...
hi T, How is the sound of the bigger Silver Mica caps in comparison to plastic and Teflon? I got the big brown Russian 0.1UF 300V type, as well as the 0.01...
Hi, ... Most Teflon capacitors I can get have magnetic steel shells and are easy to pick out in comparisons for a rather edgy, grainy sound which many mistake ...
Tks for the insight Ton silver Mica, also the proper biasing of the pre-amp stage really req lots of trial and error! All output stage like to see higher load....
Hi, ... You can considerably reduce this by doing some homework first. To illustrate, let us take a 300B output Valve at 350V/60mA/5K load which will give...
Forgot to mention Tanuski, Gary B and Keith are our members in New York/NJ. Get the beautiful Brooklyn pic. ws is member in HOng Kong. ... 91050610223749...
Thanks John for the recommendation. Dear fellow members please feel free to browse and join in the chat. That (the Gain Clone) was the Waterloo for Tanuski!...
