Fender OPT 1958 Tweed DeLuxe 50246

[CJ]

2nd type of inductance test, hold pri volts constant at 20 V-rms and vary frequency while tracking excitation current as to plot Henries vs Freq telling us about the core,

 

[CJ]

response is hella weird,  expect different after rewind,

 

[CJ]

prelim print will get tweaked after rewind as far as  modern day wire DCR, inductance, freq response,

this lady is listening to T Bone Walker playing thru a Tweed DeLuxe with Triad 50246 transformer>

This woman apparently worked in the industry.

not pulling any punches there^^

nice transformers>

Thanks a lot. This is better than TV. Uncle Doug, Brad and you are my favorite (guitar amp related) stations!

 

[CJ]

Uncle Doug? does he do the Dougie?  no not here in Kentucky.

rewind done, lucked out with wire DCR is on,

Henries shot up from 50 to 160 H due to the rotten primary wire which broke many times upon unwind,

wire colors have been adjusted from grn to blu, red and yel not org and org,

graph of Henries vs Voltage at 20 Hz shows improvement after changing out rotten primary wire,

and Henries vs Freq

Great reading for someone with an old beaten up '58 Deluxe with a replacement OPT, thank you.
No beautiful women lie down in front of my equipment when I play. Only the dog.

not much difference in square wave response after the varnish dip except at 100 K Hz,

looks like the Laplace Transform has caused the dialetric of the varnish associated with the Fourier Series to be tilted by 37.5 degrees centigrade,
which will roll off a high C at 65.8  mega hertz, given by  y(t)=A e^{{ t}} + t (cos t)+sin(t ),

which will roll off a high C at 65.8  mega hertz, given by  y(t)=A e^{{ t}} + t (cos t)+sin(t ),

Only if going at 88mph in a DeLorean!  ;D
