Just wanted to thank you for the detailed reply. I read Glydeck's web page (the one you linked to)
and
have yet to start on the 29 page dissertation but look forward to doing so. I may be your next
customer for a board. One question based on your note,... given that you targeted compatibility with
a
range of systems (575, 576, 577, 7CT1N, 5CT1N), is there any reason to prefer one (or some) over the
others as I continue my hunt?
The main problem over here in the Tek dead-zone that is the UK, is procuring a tube tester for the
project. I chuckled at Denis's estimate, in his thoroughly excellent paper, that a suitable tube
tester could be procured for $30 at a swap meet.
In the UK, such a tester would typically work out at least a factor of ten more than that, and becomes
by far the most expensive part of the project.
