I'm repairing a set of Pentas and picked up a spare broken amp. I've found almost all the transisitors were blown in the main amp section.
I do have a repair manual for them but there are three comonents not shown on my diagram or component list - can someone help please.
On the input control board (thats the board mounted in the panel that hinges out) there are two transistors (TR15 and TR16) and a diode (D10). I would be very grateful if anyone can help with what these should be and/or a better diagram/component list.
I have found other components replaced with incorrect ones so although the two transistors seem to test Ok I would prefer to check them against a known working one...
Any help greatly appeciated.
