45 100 layout question

Post by BLOOZE » Thu Jan 26, 2012 10:51 am

I m working on my 45 100 and

I wonder if turning around the 8k2 that connects to v4 pin 6 makes a cleaner built.

How are the originals wired – on the pics from amparchive ,george and chris m this 8k2 resistor is connected on the tube side.

has there been a 45 100 with preamp filter 32uf on board or should this be a 16uf - ?
i know about the 32uf + 32uf filtering

yes, originals had the 8k2 turned around (compared to the layout). they had 16uf on the preamp although the dickinson amp, and some 67 amps, had 32+32

Question was about, were the orig 45 100 or 12xxx connects the choke with the 8k2...............

I will connect it on the tube side of the board………on the layout the choke is connected at the potentiometer side of the board…………….
