[Elecraft] [ELECRAFT LIST] Using Vintage Collins 30L-1 Linear Amplifier with K2 and/or K3.

[Mister Mike]

I have a Collins Radio 30L-1 Linear Amplifier.  I would like to use it with my Elecraft K2 as well as my K3. 

I have performed a “soft keying” mod which involves modified the keying line in the 30L-1 by using a relay from -170 V 70mA (which was the original specifications) to -15V 1mA. This makes this popular vintage Collins 30L-1 linear amplifier usable with modern solid state radios without the possibility of damaging them.

I need to know if this amplifier, modified as described above, would be safe to use with my Elecraft K2 and/or K3.
