Running my heater wires and have a question.

[Mike_J]

Looking at pictures of the way sluckey runs his heater wires is a thing of beauty. The wires are wrapped up to pins 4 and 5 of the tube socket and then the two wires going to pin 9 are run in parallel through the middle of the tube. My question is would there be an advantage to running the twisted pairs to the middle of the tube socket and branch off in either direction to the appropriate pins? I am running my wires in the corner behind the tube sockets. If I was wiring from above the socket this would happen automatically.

Is there any advantage to just running the twisted wires to the middle of V1? After that it would start to get a bit cluttered with two pairs of wires. I am asking about this from a hum level point of view. Seems the answer is sluckey's method or else all heater wires would be run over the tops of the sockets. Just thought I would ask to see if anyone has done a comparison of both methods. Sluckey's method is definitely cleaner and easier to wire.

the ONLy advantage I've found that WorKs;
keep All sensitive signal wires far from filament wires, where they have to cross, cross at 90 degrees and increase distance, everything else seems to be aesthetics

Thank you for your reply. As a matter of notation I am still talking about my 5f6a bassman rebuild. The only places I see the filament wires being an issue are on V2 where the V2a plate wire comes in to V2a pin 1 and then runs across the tube to V2b pin 7 where the tone stack is run from the cathode of V2b. The only other place is on V3. There is a wire that goes to V3b pin 8 and across the tube to V3a pin 3. All other wires can easily be run so they are separated in distance from the heater wires. I would eventually transition from running the heater wires behind the tubes in the corner to overhead between V3, the PI tube and V4 the first power tube. The power tubes would be run overhead.


When I run the two heater wires as a pair to pins 9 on V2 and V3 what precautions should i take considering the way these tube sockets are wired?

Took a little more time to look at shooter's response. He mentioned that heater wires should be kept from signal wires. Pretty sure V2a Pin 1 is a signal wire which is carried to V2b Pin 7 and somehow ends up next at V2b Pin 8 where the tone stack is fed. That would mean this connection should be isolated as much as feasible so should I run the heater wires below the wire carrying signal or vice versa, or does it matter? Not so sure about the wire that ties the cathodes together on V3. Any advice there would be greatly appreciated.

Looked at sluckey's picture of his Supro. He has a cathode wire running from V1 to V3 on top of his heater wires. My guess is that answers the V3 question. Will allow for a little distance on V3 but not the same issue as V2 I don't think.

Now I am even more confused. Looked at sluckey's picture of his Mark Huss' plexi 6v6 which has some similarities to the 5f6a bassman. He is running his Pin 9 preamp wires between the sockets. Hard to tell from a two dimensional picture but it looks like those heater wires are lying right on the other preamp wires. This is beginning to make me believe that I am doing something here that I do best. Make something out of nothing. Maybe just running the Pin 9 wires together over the socket with a little room for the wire crossing V2 will suffice for my needs. Anyway I am going with it for now.

Hee, hee, hee!

Here are the pictures of the wiring of the preamp heaters and the V2 wire going into V2a Pin 1 and going over to V2b Pin 7 and the wire going to V3b Pin 8 and across to V3a Pin 3. Have a high degree of confidence that this technique is adequate. Any contrary opinions would be appreciated. Well not really but at least needed.


Thanks
