These were an upgrade in my tube preamp from Clarity caps and were excellent. I employed the larger sized caps because I was using an external crossover and needed them for proper gain. I have moved to OB speakers w/o a x-over and swapped these out for .47mf Jupiter caps so these are for sale. I used them for about 6 months. Asking $100, best offer, or a swap for some fine RCA IC's. Thanks for looking.
