5.4 Installing the Valve Bases
We'll begin by installing the 2 8-pin valve bases for the 6SH7 driver tubes.
As before, you'll want to make sure to use masking tape to secure the valve bases to the board prior
to soldering to make sure they are level. It's a good idea to review the tips we offered in the Power
Supply installation section.
Install the 8-pin valve bases in positions V1 and V2. Be very careful to align the tab 'cut-outs' on
the top of the valve bases with the tab stencils on the board. Take your time soldering on the
underside of the board as they will require a fair bit of heat and solder to adhere the pins to the
board. Again, no rushing!
