Re-capping Raytheon...

[Charlie]

I spent most of yesterday afternoon going thru the 1950 Raytheon porthole set. I have a few more caps to go, then clean out the high voltage cage (pretty dirty in there).

I found a modification done in the sound section. The chassis uses a 6T8 for both the detector and AF amp. For unknown reasons, someone has wired in a 6AV6 under the chassis and given it AF amp duty. I left the circuit as is... only replacing a cap or two going to the 6AV6.

Another modification I found is a .03 mfd 600 volt cap wired in between the yoke and G2 of the 16AP4. If anyone understanding theory better than I has Sams 99-14, please have a look. The cap connects at Line 4 (vert) of the yoke and at the top of C104 just before pin 10 of the CRT. I'm assuming there might have been a problem somewhere, and adding this .03 cap was a quick fix. I'm going with the hunch that I should remove this. Tell me what you think.

Thanks
