[HBR] HBR 6BJ6 IF layout

[john_wilkinson3 at sky.com]

Hi,I am building an HBR13 (ish) receiver. I have wired up the 2 6BJ6 IF valves, but  when I alter the IF gain, I get a bit of oscillation whe I adjust the gain from just below maximum.I don't know if it is the layout I have.Could someone post some close-up's of typical 6BJ6 IF chain, so I could get a better idea of a good layout please.If someone has similar experience, I would love to hear about your fix for this.
Many regards,John.
