J and K Audio Design output transformers: 4k2 primary and 8R secondary; gapped for 45mA (but fine for >=50mA); custom nano-crystalline double-c cores (>5.9kg each); 45 Hy@42mA; low DCR primary; extended and smooth frequency response.
Another shot of the custom nano-crystalline J and K Audio Design output transformers.
Custom nano-crystalline J and K Audio Design power supply chokes.
J and K Audio Design power supply chokes: 7Hy; ~10DCR; custom nano-crystalline double-c cores (6.6kg each!); very low DCR (for the inductance) for fast power supply recovery.
J and K Audio Design filament transformers wound on Z11 cores. Nice and solid.
J and K Audio Design Level 4 B transformers wound on Super Hi-B double-c cores. Over-specified. Lovely.
