Title: negative feedback on Prinzetone Post by: joex on August 17, 2010, 02:24:47 AM Hi, I have a Hammond OT that has the strange secondary hookups. The schematic for the Prinzetone shows the NFB attached to the 4 ohm out. The way the Hammond is wired I need to attach it to the 16 ohm out ( the same as my speaker ). Would I need to change any of the values in the NFB circuit?
On a separate topic I notice there is no screen resistor on the output tubes. Do I need them? Thank you for any help. |
