Eyelet or turret, don't matter to me - as opposed to a PCB, I can work on a PTP amp and I'm far from being an amp guru. A properly built PCB amp only gives me concern for maintenance in tracing and fixing the etchings (Mesa, THD, etc.) ... and a bad build PCB will have pots and sockets on the board, YUK! (way way too many amps to mention).
Here's a 5F1 Bluesboy that was "built in the air", with no board, just some terminal strips ...
