Any reason not to use an DY20 instead of DY13 for a 100W (EFR F4) tube?
Max current on DY13 is 28ma (although it was over 30ma when I first tested/adjusted it) and 40KV.
Max current on DY20 is 35ma and 50KV.
Max sustained current on EFR F4 is 28ma. It feels like the DY13 is being maxed out, and I’m not a fan of that. Can the DY20 be tuned down enough so 100% is 28ma? Is the higher voltage going to cause any harm to the tube?
I’m also thinking that the 1ms rise time (“to 90% power”) might make the DY20 a little more responsive than DY13.
