In a circuit like Weber's 5E3P, what type of plate voltage is supplied to the 6L6s? I see it uses the same PT as the std 5E3 kit, but specs a GZ34 rectifier in place of the 5Y3.
Also, what's the overall sound like on the 5E3P compared to the 5E3? Do you get a little more headroom before it breaks up? Does the OD sound compare at all?
If you were trying to get the OD sound of the 5E3 along with a little more headroom, is this circuit a good choice? Or maybe a hybrid of this and the std circuit? Maybe keep the fixed bias and revert to the cathodyne PI?
Thanks for any info!!
Anything from about 380 to 480 is a good idle plate voltage for a 6L6 - the lower side being better for cathode-biased amps. The more important aspect is how much plate current you have for the particular idle voltage that you have. (Current x Voltage = Wattage. You don't want to exceed the tubes' rated maximum power dissipation in cathode bias, or about 70% of the max in fixed bias)
Building a better world (one tube amp at a time)
Oh yes, taking the proper bias into account is a given
