	Add R21, R22,	1 5% 1/4W, p/n 0699-0208
6012B	In the parts list for the A1		Main Board Assembly make the following changes:
	Change C20, C22 to 0.047∝F, p/n 0160-5895
	Add C21,C23,	0.047∝F, p/n 0160-5895
	Add R20, R23,	1 5% 1/4W, p/n 0699-0208
6015A	In the parts list for the A2		Control Board Assembly change R40 to 95K 1% p/n 0699-1211 and
	1.21M 1% p/n 0699-0088 assembled in parallel. Change R41 to 200K 0.1%, p/n 0699-6376.
CHANGE 6
