Sanyo 6C-19

Manufactured by Sanyo and identical to their model 6C-19
Schematic: http://www.kevinchant.com/uploads/7/1/0 ... /6c-19.pdf

I use AA batteries from Ikea (slightly smaller in length) and also file the top down a little.
A lot of modern AA's are just too tight a fit, and on occasion they will bust the case. I have this trouble with a couple of ITT radios in my c̶o̶l̶l̶e̶c̶t̶i̶o̶n̶ queue. Lol.

Kenny, if you have CM model 6528 without a suffix letter then Sanyo 6C-19 is your schematic.

As 6C-19 is a schematic only...
...the other two with suffix A and B (with no doubt minor circuit changes) were posted for main component reference and alignment instructions.

C11 (ceramic capacitor) is shown on the trace diagram and on the schematics with an asterisk pointing to two different values. Leave it alone (it should be OK)... or if you need to, replace it with what you find in your radio. It is located in the region of TR3 and TR5

The (variable) semi-fixed resistor R15 (vr) is mentioned in the alignment procedure.

Greg.
