In Reply to: Go for the grid choke! posted by Naz on March 5, 2007 at 15:25:36:
Only thing I differ in is, I'd like to avoid the R and would increase coupling cap some but perhaps not as much as the math suggests. A slight rise at 20 hertz peaking around 7 hertz or so isn't such a bad thing. Given what most can afford in speakers I doubt it will be a problem. Due consideration to a rumble filter might be in order for vinyl lovers. I stressed a lot about but in the end things have worked out nicely.So like Naz says....go with the grid choke and don't think twice. Look at the choke's reactance at higher hertz and ask yourself what resistor can match that....and then factor in the lower DCR to keep that output tube happy....as da hammer said, "you can't touch that".
