dmac Posted January 28, 2023 Report Share Posted January 28, 2023 I have recently recapped and installed the new Pots from JKent on my 2ax and the tweeter is still very weak. My next move is replacing the tweeter with the HIVI QR1 than many here speak well about. I have seen some discrepancy on the size of the parralell coil required for this option. Since I just replaced the 4UF cap with a new 4UF cap should I use a .05mh or a .07mh coil? or is replacing the cap with a .03 necessary with the HIVI QR1? Any thoughts would be appreciated.

JKent Posted January 29, 2023 Report Share Posted January 29, 2023 Pretty sure .05 is correct but this is Roy's mod so see what he says. Another (better) option: Send the tweeters to Roy for rebuild. Quote Link to comment Share on other sites More sharing options...

As Kent mentioned, the tweeters can be rebuilt these days. If using the Q1R, first try .07mh coils. You can always unwind them a few turns if the tweeters seem to be too strong.

Jim Pearce Posted January 30, 2023 Report Share Posted January 30, 2023 Roy, I thought you stopped doing this and Chris is the only one doing it these days. Quote Link to comment Share on other sites More sharing options...

I'm still rebuilding them, Jim. I also acquired a fair number of support rings for the typically broken and/or warped flanges. Quote Link to comment Share on other sites More sharing options...
