I have had issues with the pcb that the tubes mount to on my cream board Blues Jr. I removed the ribbon cables for the pre amp tubes and hard wired the connections some time ago due to having some broken connection points after removing the chassis a few times.
I am now having issues with the power tube connections..power drops out (no sound) or odd noises. Normal operation returns if IU wiggle the power tubes. This has occured on more than one set of power tubes.
I have tried to reflow the pin connection points which seemed to help for a while but the problem has returned.
My question is are there any mod kits available to convert the entire pcb to hard wired? I haven't had it apart in a while and will do so shortly to refresh my memory. I assume it would just involve surface mounting the sockets and running the connections?
Or if anyone has done this and has any advice etc it would be appreciated.
I like this little amp. Have done most of Bill M's mods to it some years ago. My main issue with it is that tube mount pcb.
Thanks
Edit, found info.. evidently Bill at Hoffman Amp has a kit for this:

Looks perfect for me. I may use straight wire for the heater tube connections instead of slicing the ribbon cables into individual wires. Really though if the connections are ok on the main board may be more trouble than it's worth?
Would still love any feed back.
