Grover - you may have seen my 845 inquiry here about a week ago.I decided to bite the bullet and order the basics to retrofit
my sv811-10 amp to use a low voltage 845 with my 5K transformers.Do you have any experience to share with regard to interfacing
issues (i.e. drivers) that will give better results?I have parts for a number of different topologies. I was going to
start with interstage coupling since I have a pair of LL1660/10mA
units on hand. In the 450-500V plate area, I'd need to swing
about 100Vp-p on the interstage to get reasonable power out of the
845. Wiring the interstage as 1:1.125 would require me to use a
high-gain tube ; the 8532W, 6C45PI, 5842 are all options and tubes
that I have a supply of. Wiring the interstage as 1:2.225 would
allow me to do this with lower-gain, higher-current tubes such
as 6N1P and 6SN7 which I also have on hand.What are your experiences with interstage coupling?
Other options include not using interstages... There are numberous
other topologies I could resort to include cathode following
using 6BX7 or KT66.I'd love to hear about the choices and experiences you had with
different driver designs and how you landed on driver that tickled
your fancy.-- Jim
