2 channel el-84 baldwin organ amp with odd O.T.'s

[tnmgcarbide]

i have a baldwin 2 channel organ amp . one channel drove the internal main speaker array, the second drove a built in leslie cabinet. the amp was driven by a massive PT , single gz34 , and has two
OTs. i expected to have two push-pull amps , but the resistance test reveals that where a common OT has something like 120-CT-130 ohms dc resistance, these both show 120-CT-0 primary
and 0.9 ohms secondary . does that imply that these are two single-ended amp channels, using two el-84 tubes in parallel? i was aware of single ended amps that use multiple tubes, but i thought it was typically used in RF transmission .

the amp was mostly gutted when i bought it .and i can find no schematic of this particular design. the third primary wire doesn't seem to do anything. no resistance or apparent inductance.
is there a common amp topography here?

While parallel SE operation is possible, it's rarely used because it requires class A operation which means a larger, more expensive OT and less output power.

Did you lift the primary wires from the amp while measuring DCR?

Assuming there are 2 EL84s per output stage, are their plates connected?

Not clear why the OT primaries have 3 wires with SE parallel operation. But could be different impedance taps.
You should do a neon test to exclude OT shorts.

Do you have an LCR meter?

nothing is in circuit . i just have the bones of the amp. i tested them for resistance inductance and capacitance . if there were an anomaly , it wouldn't likely be in both OTs , to +/- 1 ohms on
my keithley 5-1/2 digit bench meter .

the odd wire has no obvious purpose

I agree that having 2 primary wires with zero DCR and zero inductance between them makes no sense.

What is primary inductance on both OTs?

[tnmgcarbide]

134 ohms primary, 0.9 ohms secondary dc -r

inductance of primary shows 12.6 H on my meter

[Helmholtz]

134 ohms primary, 0.9 ohms secondary

Sorry I asked for inductance not DCR.

[tnmgcarbide]

inductance of primary shows 12.6 H on my meter

Looks good.
I still recommend the neon test.
