Grannyring,
The Arizona Caps are covered on the Jeff Day Wordpress Blog you
referenced above. Check out the Yazaki-san recommended changes to
Day's system via his capacitor change and update. I think you will find it
enlightening. Yazaki-san use these in his SPEC amp and many 300B
rebuilds. Like their name I believe the Arizona Caps (green/blue) are
located in Arizona, again, I believe Day provides a link.
Yazaki-san also recommends some resistor change to Day that will be
implemented soon. In addition, some tube variants.
I am so thrilled with the cable and interconnect suggested by Yazaki-san
that I too, am going to follow his other suggestions with regard to capacitor,
resistor, internal wiring and tube types/brand as applicable to my situation.
For example, Yazaki-san just sent Day a Haltron 5u4G to try and he and
several friends agreed it bettered the tube in his already superb amp. Now,
Haltron did not manufacturer tubes, but rebrand under their name; trick is to
find out what NOS was it? Brimar? GEC? Or other British Rectifier? This
tube discussion is also on the Day Blog you reference above.
Philjolet, I don't know anything about the Belden1585a as compared to the
Belden 8402. Perhaps I should buy and compare/contrast. Can you tell me
more about it?
