Will check. Will check +B2/-B2 as well. It is possible they're a half a volt off at the moment.
How about R156? 1KΩ
The newer processing equipment make the parts a lot more consistent, that is why some mfg's can only offer one hfe grade. Good find on the Toshiba TTC004B and TTA004B but the KSC2690AY & KSA1220AY are fine as well. I used KSA1220AY and KSC2690AY to replace the blown ones on a driver pcb in a RX-900U recently.use the Toshiba TTC004B and TTA004B replacements for TR107-110 only. But, man, these new Toshibas measure much more consistently and the curves look much more ideal than the originals.
