What is Holco old style resistors ?

Søren Kramer · 4th April 2004, 08:17 PM

H4 or H4P ?
John Curl recommended Holco old style resistors for feedback resistors in Parasound HCA 2200 mod (solid state thread), current feedback resistors in my 2200 are H4. As I can understand these are the new style or what ?

H4 is the old style, still few available from Percy.

The Holco range H2 H4 and H8 were once upon a time non magnetic construction, now they have magnetic (steel) end caps that link the resistive element with the lead material (I'm not certain if the lead is now steel as well) I think this is what JC is refering to. I do have quite a few old (non mag H2) but they always were very delicate and could go noisy very easily, any strain on the end caps, I assume this is why they changed.
