Dear Sir,
I'm thinking to try your Two Terminal CCS to modify Alan Kimmel Hybrid Linecard. What sort of thing I need to do?

For further information of Alan Kimmel's circuit diagram , you can check the Welborne Labs Catalogue page A22-A26

Thank you!

You would replace all of the stuff in the plate circuit except the PS bypass caps C4 and C5 and the coupling cap(s) C2/C3. You would have to know what the bias current was in the original design to adjust the 2-terminal CCS to the same or similar value, as well.

Kevin,
Can I use your Two Terminal CCS for the Loftin-White style circuit? You can locate the circuit diagram through the following link on Figure 6.

Thank you!

Yes, you can. It needs but about 8 volts to work properly.
