Question Part numbers for Q10A-Q17A for Audiobahn A2200HC Amp?

I have a used AudioBahn A2200HC 2 channel amp I purchased that is missing Q10A-Q17A transistors ( 8 total) and need to know the part numbers so I can replace them. Anyone familiar with this amp & know what they should be? Perry, you out there? Thanx in advance.

I don't have anything on the 2200. The 2300 (the closest amp I have information on) used two different types of outputs. One used the TIP35C/36C. The other used the 2SA1303/2Sc3284. If no one can tell you definitively what the originals were, I'd suggest using the FJA4313 and the FJA4213.

Default TIP35C/36C locations

Hi Perry,

I have TIP35C/36C's on hand and if the layout is the same on the AudioBahn 2300 as the 2200 can you tell me which one goes to what location on the board? Ex: Q10A-TIP35C Q11A-TIP36C etc. Thanx!

I don't know if the bias components are the same from the 2S amps to the TIP amps. If you use the TIP35/36, you'll need to drive the amp to thermal while closely monitoring the bias current as the amp heats up. Many times, the 35/36 will avalanche at high temps causing the amp to fail. Driving the amp into thermal shutdown is the only way to know if the bias will hold.

The center leg of the TIP35C will be directly connected to the center leg of the positive rectifier and to the positive terminal of the rail capacitor.
