Attempting to repair an L 995 RV Kustom Amp.
Anyone have a schematic they are willing to share?
Other insights appreciated.
THX,
Don B.

Yes, you have the 100 watt model which is good news since we have the schematics for that on this site.
On our main page go to the technical section , the go to amps by model number.
Then scroll down about half way and click on the listing for ( K200A all )
What is the issue you are having with the amp?
Also this site does not accept photos .

Hi!
Diodes D1 thru 4 produce a DC voltage across the pilot lamp ( I302) and the two big main filter cans / caps.
With your meter set to read DC volts you should find about 40 volts positive across cap C3 and a negative 40 across cap C4.
You should find that same negative 40 volts on the non resistor side of that pilot lamp I302.
If you have voltage there then that lamp which is a type 1849 bulb is bad.
Please report back with these test results.
