Could use someone to check me on my choice of subs for 2SD438F (TR720) and 2SB560F (TR722) drivers in a Yamaha CR-620. (They were damaged when the outputs in one channel were shorted.) I'm looking at using 2SC2383Y and KSA916Y.
I used ksa916 and ksc2316 in a yamaha RX-900U restore but one is now EOL, so too bad have to make due with what we can get as new. the Sanyo bjts were usually very hi reliability so I'd only change them if blown or out of spec.
