Anybody use any of the JJ multi section caps? Anybody have any problems with them? Hum? Reliability? I just installed a couple of them and then had some hum problems in an amp that I'm servicing. So, I desoldered the leads of the new caps, to splice in some known good caps in the circuit. I've got two broken terminals now, one on each of the new JJ caps. WTF! After one solder and a desolder??? I really like their tubes but I'm having a very hard time thinking these caps are worth a damn. I'm thinking I should have held out for the German F&T caps.
