Re: Poundland 45

I doubt it was you’re fault either, only takes one knot in fine wire caused by slack in the spool when winding followed by a jerk and a knot forms if not spotted as it happens, years later insulation stress at that point shorts transformer. Nobody is watching attentively the entire time.

Re: The Audio-Talk Cycling thread.

I’m getting snags with everything I could do manually a year ago at work and in amp building. But now take two or more re-runs before it’s conquered, until next tough challenge.

Re: 801a amplifier

I’m resurecting this cosept, but in A1 only, Its a lot harder to build for A2 and the better distortion profile is found up to 3 watts per tube. By using parallel 801a’s my 5k OPT’s are just made for it. The 801a heaters are so easy two 6 v 30 watt Torroids are more than adequate power for one paral...
