I happened across a pair of BCP-16 GC NI grid chokes this week, in an old prototype chassis. Installed them in place of the 45 tubes' 270K ohm grid resistors in my shunt regulated 45 tweeter amps (with MQ output transformers and plate chokes) and was reminded of what a difference they make. I've been wrestling with some imaging issues on my system and along with beefing up the dynamic control like we know these puppies can do, the image got much better focus - quite an obvious transformation. Shawn was saying "D**n! Why didn't we do this before that demo we did a couple weeks ago?"
The only downside of this is that I have 16 more amps in the system that I'm sure will improve with the addition of BCP-16s. Time to start socking away some choke money...
