Hello All:

Ok the SD1446 has a transistor case type 211-07, which shows the white
Pill part of the transistor to have a diameter of .370 inches, or real
close to 3/8 of an inch.

The 2SC2789 Transistors have a case type 211-11, which shows the white
pill part having a .5 inch diameter.

So if the Messenger Amp has white pills approx .370 or 3/8 inch in
diameter, I'd go for it. That would indicate that it would be using the
good design of the SD1446 Transistors.

Well 2789's have roughly twice the rms of 1446's. So if it is an 8
pill 800, I would think it's a 1446......but it's just an opinion:-).
I could easily be wrong.

Hello Abraham:

I would lift or unsolder one of the ends and see the number.

Maybe M Tech is correct. But I know for a fact that the 4 and 8 pill
Messenger amps that had the 2SC2789 in them where and are dogs. Low
output, from a poor design.

How do I find out which pills it has in it?? The numbers on the pills
are almost totally covered by a bar that is soldered over them. I can
read the word Malaysia on the bottom. It has 8 of these pills.

Hello Abraham:

If it has the 2SC2789 transistors in it, I would pass.

If it has the SD1446 Transistors in it, yeah sure.

Past experence speaking here!
