Title: Three Questions
Post by: xcortes on July 29, 2010, 01:40:42 PM

I'm kind of confused. I want to build a parafeed quickie. I have the PJCCS kit. My question is, when going parafeed do I completely eliminate the 470k resistors?

Second, is there an OP modification that I should try if using a 5k load (parafeed and with the PJCCS as a plate load)?

Third, would there be any issues replacing the 100k pot with a 10k one?

Thanks,

I assume you are planning to use a transformer?

1) Yes, the resistor is not needed

2) No other mod is needed, though for headphones some optimization of impedance and operating point would be possible.

3) Quickie does not care what the pot value is. The source component(s) might.
