Another update. It seems that I ordered a pair of Heyboer reproduction Peerless S-265-Q's! I spoke to them on the phone several weeks ago and they said they'd email a PO for payment but they never did so I thought they'd forgotten about them. But here they are! And boy, they're hefty. Up and running now in an original Williamson circuit with 5881's or KT66's. They are really lovely, smooth and rich, like a nice single-malt. Lots of texture in the music, plentiful bass, but no ringing or peaky-ness that I can hear. Just very easy and musical. Heyboer did a nice job with these. I paid $400 for the pair plus shipping, but I told them to leave off the screen taps. With those I think they said $220 each. I think for an original Williamson project you can hardly do better than these.
There's a mate for my Patridge WWFB 0,95 on eBay now, auction ends tomorrow around noon. I was very tempted but I think I'll save my money. It'll probably go for more than I paid for these. Anyone wants to grab it, I've got a mate for it sitting here.
