Looking at these for my Heathkit sb-220.. anyone have any reviews on these tubes? Are they comparable to the ones that rf-parts sell.
The price is very nice too.
Penta is now just a brand name printed on a chinese-made product. I don't see any advantage to that brand, regardless of price. The care with which the tube's final processing and testing are done are what separate the cheap "poof" tubes from the good ones.
Just ordered me a pair of matched 3 - 500zg machlett tubes from Penta Laboratories in California they had them on sale could not pass up the price. this should give my sb220 more get up and go now...
