Default Hiraga amplifier and Sanken transistors

Hello,
I found this website during my web search for schematic of Hiraga amplifier:
http://member.newsguy.com/~stigerik/...asse_a_20w.htm
I think, it is original schematic of this amp with PCB made by website owner. I have a question about use of Sanken transistors for output devices.
Can I use Sanken 2SA1216 and 2SC2922 transistors instead of D188 and A627 from original schematic?
Thanks for the help !!!

I will assist you question. I "found" two good pairs in my scrap box and am tempted to use them in this amplifier. But me too, I am not sure if they are fully suitable.

Hello lohk,
I did search the forum for answers, but I could not get information about Sankens in reference to above schematic. Usually, transistors are being discussed on higher knowledge level than I have. Recommended replacement for Hiraga amp are MJ series from Motorola ( On Semi). I have also found very good opinions about Sanken transistors. I wonder, which are more recommended for Hiraga ? I would also have another question about Sankens. If they would be recommended for this amp, can I use them as direct replacement, or circuit has to be changed to accomodate them?
I hope someone will be willing to help us...........

Maybe you could download the data pdf for them and compare them if they have similar charactistics, voltage, amps and so on

Hi Fritzell,
Yes I will do that. I did not want to be leasy, I thought someone already did the comparison. I do not understand all parameters. Usually there are some differences among them. I will try.
