Hi TD and Mikelap,

 

Thanks for the suggestions and help.

 

Do you think these will work, i.e. can be unbolted?

Those look like they can for sure!

maybe you can reach the screws from the holes for the gain jumpers with a screwdriver?

From what I remember from the pictures of the circuit boards in the MKIII there are several boards one above another so I don't think that this is possible.

No there is just one board and it is a whole lot of fun to get in and out. You have to bring it forward halfway to unsolder the front heater wires, then back halfway to get the other wires. After that you can slide it out around the transformer wires. Front and Back panels have to be removed. 4 screws on top of the chassis hold the board in. smily_headphones1.gif

Hi TD,

 

Thank you for clarifying the board layout. I don't feel that I am proficient enough to tackle the task of removing the circuit board.

Waiting to hear from China if the adapter set above can be unbolted - the one adapter I have (different) is riveted.

hope this help if you recall this picture i posted awhile back and you can take apart and put back the 9 pin adapter alot easier than the Vector(see the 9 pin adapter installed in MK III)

Since I want to use octal tubes it seems to me that the adapters for octals are wider and will not fit inside the ring.

I think the easy and ugly solution is two adapters plugged together. The first adapter, the ones you referenced, are simple socket savers, which would act as "risers" to essentially move the "base" of the LD socket up above the rings. You don't have to take them apart. Just plug them in.

And then you would have the octal to 9-pin adapters, with 9-pin on the bottom and octal on top, to allow the use of 6SN7s. Just plug them into the first adapters and you should be good to go.

Whoo Hoo...
It will look like the "Rocket to Russia", or MIKELAP's "Nuclear Stacks", my "Tower of Power" or ILM2's "Apple Antlers"

I just love it!

Or just pick up a MK9 and roll all the octals you want...
