Re: [Frameworks] Pageant AV 12 E6 sound problem

Thanks George, and Colin, for your advice – nice to know I can probably replace 
a fuse though getting to it seems a little daunting. Thank you.

I could not locate a diagram for the Pageant amp but most of the projector amps 
of that period powered the exciter lamp with a high frequency oscillator. It 
was difficult to generate a pure DC voltage for the lamp. 

The high frequency ac was above what the ear could detect. If you can find a 
tube tester test the tubes or look for one that has no glow when viewed in the 
dark. If it has a transistor amp ignore this advice.

If you can locate a diagram forward it to me and I will see if I can be more 
specific.

Hi Frameworkers, I have a Pageant AV 12 E6 where the optical sound bulb is not 
coming on. I’ve replaced it with a new one and it’s still not working (the old 
one didn’t look burned out either). I know the amplifier is working as I hear a 
healthy hum when I turn it on, and the flash from my camera even caused a loud 
pop when I snapped this photo, so I know the reader sensor itself is working. 
Any idea what could be causing the bulb not to come on? There’s a “circuit 
breaker” button on the panel but it doesn’t seem to do anything when I press 
it. Is there a fuse somewhere inside that might need replacement?

Re: [Frameworks] Pageant AV 12 E6 sound problem

[Colin Brant]

Hi Scott,

I am not certain about that model, but on similar models there are several
(usually 2-3) soldered in fuses. They are not easily accesses and require
lifting the whole front panel and gearbox up out of the wooden shell. Then
they are located in the center rear of the projector. I have replaced one
of these to fix a problem with the main lamp, but without a wiring diagram
it's hard to know for sure about the sound lamp circuit.

Perhaps this is helpful?
