Patient: K7203
Symptoms:
1. High b+ 139 and not 121. Couldn't adjust down far enough.
2.Squealing / High pitch sound
Solution: replaced cap c009 22uf. Caps on these usually fix a lot of issues but just replacing c009 fixes the noise and the b+. I was able to adjust b+ enough once I replaced c009 So a bad c009 caused high b+ which caused the noise.
several caps were bad, however C009 was the very first one I tried
