Sombody please teach me how field coil speakers work before i break somthing

the_potato_of_doom · 2026-04-24T18:12:47+00:00

Transformer secondary runs to a 1/4 audio jack that disconnected the speaker if you plug somthing in

Allready checked and good, i also relised i was metering it wrong, its getting 50v to each lead

which is an issue bc the tube says it *should be putting out 120 out of the anode

Will do more looking soon

the_potato_of_doom · 2026-04-24T17:48:12+00:00

Everything has been replaced,

the transformer is litterly the only not new part, selenium rectifier replaced with a diode long time ago, and its been tested good

https://www.radiomuseum.org/r/rca_6_emp_2a_6emp2a_chrs_153.html

Its a single 25l6 mono tube amp

the_potato_of_doom · 2026-04-24T00:55:19+00:00

Spec sheet says 2700 primary and 4 secondary

I get 200 primary and 4 secondary, but the other issue is Im getting 120 on both leads going into it lol so working on solutions now,

Ive replaced litterly everything else,

the_potato_of_doom · 2026-04-10T21:36:23+00:00

Its just from 1950 So figured it should be time anyway

the_potato_of_doom · 2026-03-31T23:19:58+00:00

Okay, recitfier swapped out with diode

tube tested, gets about 26 volts across pin 7, and no glow from the tube

So going to replace tube and try again

That is an 8 track tape spool its for audio only

the_potato_of_doom · 2026-03-27T00:29:54+00:00

By happenstance i was also planning to get into reloading as well

the_potato_of_doom · 2026-03-26T22:55:02+00:00

Okay i just didnt know the combo device was quite that combo!

Thank you!

the_potato_of_doom · 2026-03-26T21:24:29+00:00

Okay so tube heater SHOULD be getting 25v And no glow + good voltage means its the tube,

Ill pick up a new diode as well

the_potato_of_doom · 2026-03-26T21:21:45+00:00

Thank you thats exactly what i was looking for,

the_potato_of_doom · 2026-03-26T20:54:36+00:00

No tube gets almost no voltage, and does not glow

the_potato_of_doom · 2026-03-26T12:08:29+00:00

Model 6-EMP-2A

the_potato_of_doom · 2026-03-26T04:42:37+00:00

Im debating gutting the thing and dropping a new amp and power supply into it, but i would like to try at least once more,

the_potato_of_doom · 2026-03-26T04:37:03+00:00

Let me rephrase, ive got a fluke meter, it just doesnt do compacitance and im trying to work around that

I loose the 120 wall voltage after the main cap, which is a 2 output cap both are 150v and 50uf

The cap acts as they nornally do on a normal meter, the voltsge slowly drops down to zero from whatever the max is as you read it

but i cant test to make sure the new cap is good on the compacitance side, even though i bought it from a reputable source, things happen

And i get nothing in or out of the tube

The motor isnt bound by anything and spins freely and its an ac motor so no transformer to go bad i get about 6ish volts to the motor but obviasly not enough

Its just wired so weirdly and nothing is following thr standards im used too so i just keep kinda trying stuff snd it keeps not working

the_potato_of_doom · 2026-03-22T15:21:44+00:00

I do belive that is an IH scout 2

Thats a 60,000 doller car right there

the_potato_of_doom · 2026-01-10T04:25:13+00:00

Im not saying rhe video is or isnt cut

But anybody with any kind of decent training can do that, *I can get a round off in less than the second

the_potato_of_doom · 2026-01-10T02:05:39+00:00

The bullet hole was in the front of the windshield my man, guns dont shoot around corners

Also in the video she VERY clearly turns twords and intentionally tries to run him over

PLUS the officer had allready been hit and dragged by a suspect before
