Socket Extensions (revisited)

[squiffiness]

I've read a couple of older threads in this forum regarding socket extensions.

Will [shortly] begin building a SimpleSE. For heat management, it is clearly better to mount all the components on the silkscreened side of the board.

However, doing so prevents mounting the board inside a conductive chassis.

Anyone have any experience using any of:

1) Chassis mount 8/9 pin sockets and wiring the sockets to the PCB

2) Using some method of long pin PCB mount sockets (like Beltons)

3) Fabricating pin extensions like Tubelab shows on his Tubelab SE build site

4) Using NOS "socket savers".

I have read that extending the socket could create some side issues related to tube performance (oscillations, THD effects, etc.) or unexpected consequences.

Thoughts?

My Tubelab SE has been running for a couple of years with it's components under the board without issues....

If you are worried about heat, then provide adequate chassis ventilation. Think about serviceablility as well. You will most likely need to measure voltages across a few things when getting it up and running.

Chassis ventilation is a given in the design. Just thinking that since heat flow will be upward, items on top of the board with some clearance around them (e.g. resistors over 1W dissipation, U10/20 and the TO-220 diodes) would benefit.

I know I'd asked about mounting before in a previous thread.

I am also interested in what sonic and electronic performance issues might arise by using either chassis mounted tube sockets and wiring them to the board for more clearance OR using some form of pin extensions to do the same.

My hope is to hear also from a few of the testers in the audience and maybe Tubelab George himself about the pros/cons of elevated or hardwired sockets.

Danke.
