Thinking to build ​6CY7 SET (​forum)

Suggest in forum ​here to use an alternative output transformer, the ​GXSE5-55K.

Notes: "Check your plate dissipation. If it's above 5.5W then drop the B+ a little. If not, then leave it alone. My guess is that you're probably fine." (add 100 ohms in B+ if needed)

Rough cost estimate:

2  6CY7        $ 6.00    $ 12.00
1  6CA4        $15.00    $ 15.00
1  269EX       $48.23    $ 48.23  Power transformer
1  193H        $37.72    $ 37.72  First filter inductor
2  154M        $12.80    $ 25.60  Second filter inductors
2  GXSE5-5.5K  $20.12    $ 40.24  Output transformers
                         $178.79  Total above
