I must say that I have always thought the Cardas "Golden Ratio" schtick was pretty lame. So it was with no small measure of trepidation that I sent off a rather outlandish sum of money for two Cardas Golden Whatever 4.7 uF caps for th...

A visitor of my site, presumably it is someone from GOTO, sent me email informing that GOTO made a new midbass horn. My enthusiastic applauses to GOTO as former GOTO bass-horns were very bad and not serious.

I have lately been comparing the stereo and mono versions of many recordings from the 50's, and I have found that even when using the same stereo needle and closely matched for stamper number, the mono version is consistently better than the stereo v...

Well, I think you missed what I aimed. It is not the question how much Srajan own or Srajan’s writer’s mind was spend to cook up the 6moon articles. You would hardly see any analyses, research or any attempts of demanded assessments at 6moon, or any ...

I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. I can get roughly 70Vrms out of it. Output stage clips first, driver continu...

Romy, Here are some images of a slight variant of your Macondo Frame proposal.
This version has the Fundamentals horn more rigidly coupled (this may or may not be desirable) and does not require a counter weight. It may also be a little more co...
