I did mean R2. I'm sorry for not being clearer. Many thanks for the information. I'll try with a 120R in parallel using ugly construction and report my findings. If that works I might try find out if I can still solder SMT devices.

To get any reasonable slew rate R2 needs to be closer to 100ohm not 1k.
What would you recommend for the I/P side? I.e R1.
