Re: Trouble with WG6100

Noel:

Sorry, should be Q604 NOT Q607. I will look at the part from Bob's kit
tonite. I replaced the 4 transistors on the heat sinks with NTE48's and
NTE49's.

Q607 on the deflection board. Q604 and Q704 are two of the four transistors
with heatsinks on the deflection board. Gregg Woodcock's article recommends
upgrading these from the original MPSU07 (or NTE188) to the beefier NTE49.
I have done this a half dozen times on P314 and P327 revision boards with no
ill affects. Would you mind if I asked what part that Bob substituted for
these?
