Does anyone know where I can get the following capacitors for the Mac+ - 1. Board ref. C4 - .033 mfd 400V metallized film cap. 2. Board ref. C40- .03 mfd 400V ceramic cap. Also - Board ref. R7 - 39 ohm, 5W, 10% tolerance wirewound resistor. Failing that, does anyone know what causes the linearity of the Mac+ to be off? I'm using the Test Pattern Generator disk from Larry Pina's book, and when I do the crosshatch test, some of the squares are less than 1" sq., and some are greater than 1" (by about 1/16" at most). The balance test shows the propellor circles compressed a bit on the left side, and stretched on the right. I don't want to send the board in, since I already replaced all the big caps, as well as the flyback transformer, and some other parts that came with a power supply upgrade that I ordered. Most places only do complete board repairs (swaps), or charge a flat rate (about $150). Any help appreciated. Peter D.
