Yes, the transistors will not make it. Motorola designed it that way.

Still be careful !

and see if the repeater can be brought up. If it does, you have an
internal path somewhere.

I had one of these in the ham band for several years. I disabled the final and

worked great with only about 6 watts out of the driver. With the tube final

If I understand Motorola right, this is would serve the same purpose
as a audio delay board to remove the squelch tail heard on the unkey
of the mic?
Also, how clean do you think the amp might be down at 145.410 MHz and
not be spurious? I am sure there will be a reduction in power, but

No it just buffers the COR no audio delay.
The amp will work at 145 it will just not be as efficient. That should not
be a big problem.
Just stay within the limits of the tube.

Looking at the amp I don't see the low pass filter that you are

Actually he put everything he owned into a storage facility and now everything

Maybe he'll just have to use good old RG214 and crimp-on N connectors like
Celwave did on the stock cable sets they sold for $250 (I bought one).
