OK, here's what I have now that I am back in town:
Paramount 2A3 original design: target was 55mA, can't use the BCP-15. Use the stock choke or the Magnequest BH-7. Target parafeed capacitor is 5.6uF for either, with the stock 3.3 up to around 10uF being an acceptable range.
Paramount v.1.1 (soft-start) 2A3 : Properly adjusted, the current is 50 +/- 2 mA, so the BCP-15/50mA or the BH-6 (Paramour upgrade) plate chokes are acceptable. (Note the Paramour upgrade transformer BH-5 is the same for Paramount or Paramour.) With the stock or upgrade BH-5 output transformer and BCP-15 or BH-6 choke, the parafeed cap is 10uF, range 5 to 18uF acceptable.
Paramount v.1.1 (soft-start) and a 45, using a 6K cathode resistance (two 3K resistors replacing the 2K resistors in the stock amp), and retaining the stock or BH-5 output transformer, the plate current is 35 +/- 1mA, so the BCP-15/40mA choke is acceptable. In that case, the parafeed cap would be 12uF, range 6uF to 24uF - assuming you retain the stock or BH-5 output transformer. NOTE: I separately have advised jrebman and Paully on specific changes, such as different output transformer impedances and cathode resistor values, and assuming the power line voltages at their houses. Those recommendations are not general ones, they are specific to their situations only.
Original Paramour and Stereomour 2A3: The 2A3 cathode resistor is 1200 ohms and the bias is 60 volts, giving 50mA plate current. So the Paramour II upgrade BH-6 or the BCP-15/50mA (Original Paramour upgrade) are suitable. The original Paramour upgrade transformer (not by Magnequest) was a 4K primary impedance, same as the Stereomour stock transformer, so the parafeed cap value is 5uF, with an acceptable range of 2.5 to 10uF.
Original Paramour and Stereomour 45: The plate current is in the range 35mA to 40mA, so the BCP-15/40mA can be used. Assuming the 4K transformer impedance as in the 2A3 versions, the parafeed cap would be slightly larger, 6uF with a range of 3 to 12uF. Using a different output transformer impedance would call for some other changes.
Paramour II 2A3: This version of the Paramour design uses the Western Electric automatic bias (a.k.a. "split-rail") scheme, where the driver current as well as the 2A3 plate current goes through the 1100 ohm resistor. The total current is 55mA, of which 50mA goes through the 2A3 plate, 4mA through the driver plate, and 1mA through the driver C4S bias. So the Paramour upgrade BH-6 or the BCP-15/50mA are suitable, same as the original Paramour and the Stereomour. If the stock or BH-5 output transformers are used, then the parafeed cap is 10uF, with an acceptable range of 5uF to 20uF.
Paramour II 45: As with the original Paramour and the Stereomour, the current is below 40mA and the BCP-15/40mA would be acceptable. The BH-5 output transformer (3K impedance) would normally be used, calling for a parafeed cap of 12uF, range 6uF to 24uF.
Man, I hope I covered everything and got it all right this time!
