TRX2 Spur Elimination Option

How do I get hold of the Spur elimination Option - it would be good to
combine the two. I can't see it in the shop

Thanks Matti - The capacitors _are_ brown, but so are the replacement ones I got from Farnell. I also got a set of film capacitors Farnell 969-5087, PANASONIC - ECHU1C473JX5 at 42p each, and these have almost completely cured the problem. The PCB no longer is sensitive, but the individual capacitors...

TRX2 Microphonics

Any advice on microphonics on the TX2 main PCB? Turning the audio gain
right up with the loudspeaker attached to the case causes the set
to oscillate. The most sensitive components to tapping seem to be C4-7 and
C12 - 15 imediately after the mixer

Thanks all
