Re: 184 Time Mark Gen. - 2nS & 5nS not working
ISTR I improved my 500MHz oscillator's output by modifying the coupling in the L69/L70 transformer.toggle quoted messageShow quoted text
Yup, I pushed the L70 wire so the two halves of the transformer were closer together :)
I also kept in mind that the purpose is to provide timing accuracy, not amplitude accuracy. Sometimes life is too short.
Oh, I did buy a NOS nuvistor for around £10.

I've had three 184s over the years, and I've never had one in which the 2 and 5nS sections worked correctly. I gave up trying to fix the last one. Maybe if you get some good leads I'll give mine another go (since I have so much time on my hands anyway!)
