DSL 50 Tube Board rework

[AmpFix]

Has anyone here modified a DSL tube board to take the power tubes off of the board itself and onto the chassis? Better yet, anyone here make a new PTP board?

I was thinking of cutting out the tube sockets on the PCB with a dremel tool and hand wire the EL-34 tube socket on the chassis. I'd clean off (remove) as much of the traces as I can and use wires as much as possible. I'd also hard wire the bias circuit (get rid of those PCB to PCB connectors)

This should be easy enough to do and should help in terms of taking high voltages and heat off the board.

I can't say I have experienced any problems with high voltage on the boards, nor for that matter heat, really. When tubes fail, sometimes screen resistors burn up. In the 100 that little C46 cap sometimes shorts and leaves a little burn around itself, but I don;t think it is in the 50. I have seen darn few arcing sockets, but again when they arc it is hardly the circuit board's fault. Once in a while the preamp tube heater bridge rectifier doesn;t solder in well and that heats up. But that is easily solved with a proper installation of a bridge.

If you want to rebuild your amp into point wiring, fine. I'd just have to observe the reasons stated don;t convince me.

Are you saying that you've never seen any issues with the Marshall JCM2000 DSL boards? Some people say that the boards are bad quality. I've never had a problem with mine, never.
In saying that, I don't like the fact that the tubes are mounted on the PCB and I think that it would be a cool project to wire up a turret board style board for the tube board only. I started drawing the layout and its actually a pretty simple board. While I'm at it, I could put in top quality components and improve the reliability by having soldered connections for things like the various connectors (especially to the bias board).

I have had any number of problems ON the board, but never any that I would attribute to having happened BECAUSE it was on a board. For example screen resistors burn up, not because they are board mounted, but because tubes fail.

I see failed solder joints on circuit boards, yes. I also see Fender Pro Tube hand wired sockets that were never soldered at all, or without a full dose of solder. No circuit board to blame there.

What circuit boards are not made for is repeated multiple part changes, the sort of thing the mod-crazy folks here like to do.

There is nothing wrong with the boards or the parts being mounted to the board. As Enzo said the amps have some issues, but nothing caused by the board itself.
