Pioneer RT-707 low / distorted record. Playback is fine. Replace Q301,302 (2SC1344) with KSC1845 and Q303, 304 (2SC1213) with KSC2383. Board is marked B and E for the appropriate pins.
I did a full recap on my 1978 707. I did replace all the ceramics with Wima Film. Many of the capacitors where more than 20% out of spec. Thought about replacing the transistors on the play oscillator board but mine plays and records pretty good.
