Amp is using the MMBTA56's and 06's as the drivers in the power supply..

Will the MMBTA42 and 92 work in there place ??

I have used MMBTA56/MMBTA06 and MMBT3904/MMBT3906 and had success with both.

I have not tried the MMBT42/MMBT92, you could try them and see.

The 42's/92's are for high voltage applications with specs almost 4 times the original part.

I would use the originals......you might want a second opinion.

The 42/92 have lower gain and may not work well. The others suggested will work properly.
