Lou wrote:Billy I have your layout diagrams and like everyone else I am truly thankful that you have taken your time to make those drawings. I have built a '68 12xxx series metro amp and I am unsure what the best Grounding Layout to use as the filter section is different than a 1959.
Do you have any suggestions for me?
Thanks in advance
Lou
v1-v2 cathodes grounded on pot buss between the input jacks and first volume pot -
the pot grounding buss( the presence pot is not in this buss ) should be grounded to the choke screw under the main board closest to the front of the amp. run a wire from your buss to this screw with a lug there
preamp cap on main board goes to same screw as the pot buss
pt grounds on PI cap screw closest to the front of amp along with the bias supply and mains grounds.
screens ground along with PI cap and presence on the other PI cap screw towards the back off the amp.
the ac plug gets its own screw and lug ( i threw a lug on one of the PT mounting screws.
happy building!

I guess I may soon enough. I may have more time soon but there are JTM45 layouts like mine out there. Plenty actually. Its why it was low on my list of priorities.

Yes there is. And I know I'm months overdue to help host them...
Let me see if Bash can get them copied over to our new server.
Thanks

Which PDF is of a 12xxx series board? (filename please)
I'm guessing it's the "67-68 Super Lead Layout.pdf"
