Single Ended Triodes (SETs), the ultimate tube lovers dream.

In my direct-coupled 45 amp....some observations

The direct couple run from the 7B4 to the 45 sounds more detailed with a single run of .22 gauge silver than it did with the same wire paralleled with two TCSS.

On the 45's filament going from three parallel TCSS to a single run of TCSS was an eye-opener, more pratt, detail, dynamics and strangely to me, better articulated bass. Same findings on the filament's center tap lead.

When I built the thing I replaced the stock B+ and plate leads on the Electraprint output transformers with three paralleled runs of TCSS.
And thinking I was on a roll based on the above findings, I snipped out two runs of the TCSS. OMG! Big mistake! Sound was flat, thin, anemic, and lacking in bass. What a bloody A pain that was to remove the transformers and put the three runs of TCSS back!

So: It's not so much the gauge and quality of the wire but where in the circuit the wire is.

On a side note: on the Electraprint website, Jack advised to NOT twist the high voltage secondary leads. Anyone care to comment on that?
