Blown outputs (maybe?) in my Forte' 3 amp.

[gullaz]

Hello to all Pass Labs forum users. This is my first post on Diyaudio.
I have blown three output transistors on my recently acquired Forte' amplifier while trying to adjust the bias...
The amplifier was running rather cooler on one side so I opened it and tried to correct the difference measuring the amperes... Result: three devices on the left channel are probably gone as well as two of the emitter resistors and when I try to power it up it blows both fuses.
As a total noob I was very imprudent to mess with something I don't know...
Now my problem:
As original toshiba outputs are difficult to find
(they are [FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica]2SC3281/2SA1302) I have found out that possible replacements are [/FONT][/FONT][/FONT][FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica]2sc5200/2sa1943... In this case may I replace only the three blown outputs with the new equivalents or should I replace all the devices in the left channel or, worse, replace all the devices in both channels (ouch!!).
Sorry for posting such a simple and banal question but I thought that here there might be many users that know this amplifier and can advice me for the best.

Thanks in advance for any kind answer you will give me. [/FONT][/FONT][/FONT]

Likely you could replace just the blown devices without
problems. Most audiophiles would be bothered by the small
asymmetry of such an approach (or by a splice in their
speaker wire).

Thanks a lot for the answer mr. Pass, I was only concerned by possible reliability issues... This cheers me up a lot: I'll change the burned devices only (and control the left channel bias trimmer which was probably gone.
