Twin65 reissue tube order and speaker wiring

[Skiroy]

Hey guys,
I was wondering if you could tell me if the speaker are wire in parrallel or series? I changed them out and could remember if the first speaker + and - went with the second speaker's + and - or if the 1st speakers + goes with the 2nd speakers - and the 1st speakers - goes with the 2nd speaker's +?

Also if you could tell me what tubes are what in the 65 reissue twin that would be greatly appreciated.

Im trying to trouble shoot what shoot like a bad tube or blown speaker.

Twin Reverb OT wants to see a 4-ohm load, so...

Two 8-ohm speakers, wired parallel for a 4-ohm load is the standard configuration.

Always a good idea to draw a picture or take a closeup snapshot and label things before taking them apart.
There should be a tube chart in the chassis.

Looking at the back of your amp, starting on the right are small preamp tubes.
V1-12AX7
V2-12AX7
V3-12AT7
V4-12AX7
V5-12AX7
V6-12AT7
Then you have the 4 power tubes.
V7-6L6
V8-6L6
V9-6L6
V10-6L6
Twin Reverb has SS rectifier so no tube.

Im trying to find out which tubes go to which channels and reverb and tremolo to narrow which ones to swap to try and get rid of this bad distortion.

V1 = normal channel preamp
V2 = vibrato channel preamp
V3 = reverb send
V4 = reverb recovery and extra gain stage for vibrato channel
V5 = vibrato
V6 = phase inverter

Thankx
Is v7 and v8 power tubes for the normal channel and v9 and v10 for the vibrato channel or do all 4 power tubes work together?

The four power tubes work together in a parallel/push-pull configuration. The channels are mixed together before going into the power section.
