Hi, Looking for some recommendations on refreshing some valves on my Audio Innovation 500s amplifier. At present the back 4 ( Edicron 5881)
have done around 6000-7000 hours of sterling work but was wondering if anyone has tried any different ones, kt 77 seemingly to be popular
amongst some folk, judging by internet archive material ?. I have recently replace psvane ecc83 with some mullard + brimar s to good effect,
amazed at the improvement in clarity and realism of instruments etc. I have also 2 bugle boy 88 s and border patrol power supply btw.
Thanks for looking and best wishes.
