[Heath] Parts for IP-27

[Kenneth G. Gordon]

For those of you who may wish to replace that 3000 MFD 75 VDC cap in 
your IP-27, I chose the following part from Mouser for that purpose:

Mouser Part Number (P/N) 598-DCM302U75AB2B  75V 3000uF
Price: $16.23

To mount it, I used three of those square, stick-on "feet" sold in packages of 
8 by Radio Shack. I stuck one over each of the three legs of the mounting 
ring with the sticky side towards the clamp, then inserted the capacitor, and 
tightened the clamp. This holds the new, much smaller, capacitor perfectly in 
place. By loosening the clamp slightly, one can rotate the new cap into 
perfect position for attaching the necessary parts.

For those of you who want to make the "spike" mod to prevent the paralleled 
pass transistors from failing when the voltage-select switch is rotated too 
quickly, the following Mouser parts apply.

Capacitor, 0.015 uFd, 630 Volts, Mouser P/N 647-QXK2J153KTPTZH, price 
$0.89.

Zener diode, 56 V 5W, Mouser P/N 863-1N5370BG, price $0.72

As soon as I can, I will post a .JPG of the mod (by Heathkit, BTW) at this 
website:
