I picked up a late serial number D-150a series II that has several damaged parts I want to replace. One such part I'm having trouble with is Q112 (C4116-7) which is listed as an NSD206 pnp transistor. I've been unable to locate one or a possible alternate the 2N6556. Does anyone have any suggestions ? A 2N4920 seems possible however the specs were lower. Any help would be appreciated.

thanks

I have a D-150a series II and was wondering what the sequence the IOC lights follow....when you turn the unit on they both blink then turn off, when you turn the unit off they come on bright then gradually go out. Is this normal ? The amp sounds good and quiet... Are there other sequences that show a problem  other than flashing if the amp is clipping at high volumes?

thanks
Tony
