Choke ratings for Matchless Spitfire

Don	Choke ratings for Matchless Spitfire Hello all, I'm thinking of building an amp based on the Matchless Spitfire schematic located in the "schematics" section. I've got a nice old Knight amp that has the same basic configuration, and it will be an easy mod to make it into a Spitfire. Anyway, there's a filter choke shown on the schematic, but the stats aren't mentioned. What should the mA and henries rating be? Also, where could I get one? Thanks in advance for any help. BTW, my last DIY amp project--a '59 Bassman front end feeding four 6L6's in a parallel, push-pull, Class-A arrangement with an all-tube effects loop via O'Connor--came out great thanks to the help I received here. It's as quiet as can be--virtually no hum--and sounds remarkable. I'm currently building a 4X10 cabinet out of cedar loaded with four WeberVST C10R's in it. I got them for $15.00 apiece, so I couldn't pass them up. I'll let you all know how it sounds as soon as I finish it. Cheers, don daput@pe.net Idyllwild Brewing Company
