Thanks Gary,
Took a look and also at the pages to which the site links. Opened up
quite a few PDF's for the various valve bases for the 250b. Looks like
the SK600/610 has a 2700pf decoupling ring whilst the SK620 has an
1100pf ring.
I'm guessing therefore that the 600/610 is for HF use and the 620/620A
id for VHF/UHF use.
Regards,
Ken
