My EAR 859 is on and working as I write. Its home-built of course, working on its original valves! I used high grade caps, like paper/oil, in critical parts, and transformers from TdP. Drives PMC IB2s loud with ease...

Congratulations for your amp.
Could you share your experiences on all (intentional?) error related to schematics published by HFN? I have been aware of 2 errors so far, 47 k instaed of 4.7k and 4.7 pF instaed of 47 pF...there must be others I'm interested so much.

Default Errors?

Hi, Sorry Obi, I was not aware of any errors. I built my amp to the circuit diagrams published in 1994 in HFN. On the magazine copy I have here I can see there are 2x 47pH caps in series on the anode of the PL519 (I used 40V heater valves) but otherwise I know of no errors I'm afraid. I'll be interested to know if there any mistakes in the original article???

I guess I could compare the diagram published on the web with my paper copy? Please do let me know if you find anything, I'll have a look over the web diagram in the next couple of days.

Thanks, Andrew
