Screwed up my Crack upgrade

[flyfisher55]

Everything that I in error labeled as "0" is in fact 0.L m ohms. My apologies.

[Paul Birkeland]

I would recheck Q1B on the big board.

[flyfisher55]

I need steady hands, someone to teach me ohms law and a drink!
ok don't ask me where I got those previous numbers but this is what I'm seeing now .08 L+R, L+C .09, R+C 0 all M ohms

Is R+C 0, or OL?

If it's 0, then that's a dead transistor.

[flyfisher55]

I'm seeing zero

[Paul Birkeland]

She's toast! (I'd replace them both on that side)

[flyfisher55]

what about the others and my wacky readings? These parts are cents ... Not better off just swapping all parts in question?

[flyfisher55]

also the issue with small board still not working after having removed the large. Do we need to replace parts there?

[Paul Birkeland]

You can do the same readings again on the small PC board to check for shorts.

Again, it's low impedance values between any pair of transistor legs that mean a problem.  If there's an "M" in the reading or it says "OL", those are OK readings.

[flyfisher55]

Sorry it took me awhile...

these are the transistor readings from small board
Q1A- L+C 32.23 m ohms
        L+R 0.L m ohms
        C+R 37.78 m ohms

Q2A- L+C 0.L m ohms
        L+R 28.10 m ohms
        C+R 16.85 m ohms

Q1B- L+C 33.0 m ohms
        L+R 0.L m ohms
        C+R 38.25 m ohms

Q2B-L+C 11.36 m ohms
       L+R 000.7 m ohms
       C+R 11.52 m ohms

[Paul Birkeland]

Q2B looks to have a short.

[flyfisher55]

Should I order defective parts from an electronics part shop online or through Bottlehead?

[Paul Birkeland]

Whichever is easier.  There are a decent number of local electronics shops that will carry the NTE line of semiconductors.  The NTE123A and NTE198 are the equivalent transistors that go on the larger PC board while NTE159 and NTE39 go on the smaller board.

Hello Paul, I'm back to trying to restore my crack. I ordered parts online and replaced the parts in question. Here are my results on large board OA- OL
                 OB- OL
                 G- 0
                 B+- OL
  02B heatsink hot

LED nearest outside rim on B+ side lit
Both LED's on left side of small board lit
One LED at vaccuum tube base lit
All other LED'S are out.

I'm presuming the problem has to be traced so I removed large board.
