Many thanks for that info John. So, it looks like I would do well to use a pair of 5k6 on the anode and grid of the Homage?
I'll see what I kind find on the 159; that had escaped me.
Non-believers may challenge the idea that these were the best GDO's ever made, but it's looking likely that they were the most expensive
. The budget for the Homage is about GBP20, and much of that will go on the frequency counter.
