DavidDru Posted October 20, 2016 Report Share Posted October 20, 2016 my 2ax's were the same way. I think you have pots in need of attention. Those SOB's are the unfortunate weak link now that they are the age they are. Of course it could be something else but if that clarity and sound is just coming and going it probably is just the pots. find a sweet spot somewhere by adjusting the one that appears to be the culprit if you can, but they need to be removed and cleaned to see if they are still viable. If needed to isolate which driver it is that is coming and going, use a paper towel cardboard roll to listen thru up against each. Many a threads on here that run through how to deal with them including the AR3a restoration manual that Roger pointed out. Do your research here by reading thry threads and you will find answers. Otherwise keep posting. Funny thing, The AR might be a what you would get combining KLH with CV! Great mid and high tones with bass that can drive.
