I did it on an AL-1500. It came with photocopied, hand-written notes by Tom
W8JI.
It was simple. I think I may have skipped drilling any holes and mounting the
PCB with just two standoffs - I don't remember. I think I had to "stretch" a
single wire.
If the process is "graduate advanced calculus", I'm a f**king nuclear rocket
scientist. With a Nobel prize.

Subject: [Amps] Replacing T/R Relay in AL-1200.
I need to replace the old 3PDT relay in an Ameritron AL-1200. Luckily,
Ameritron sells a PCB relay assembly which replaces the clunky old relay with a
more modern, faster relay.
In looking at W8WWV's website he describes replacing the old relay with the new
assembly as "graduate advanced calculus" and estimates the time to do the mod
at roughly 8 hours, requiring drilling 3 holes, etc.
To further complicate matters, the tech at Ameritron I spoke with says the new
assembly comes with no instructions...not even a schematic!
On the other hand, another amateur I emailed said it was easy to do, about
1 hour.
Can anyone else who's done this procedure offer any additional insights?
Anyone
make any notes when installing the mod? Thanks!
73,
