The Electronics Universe

Tell me more about that scope you mentioned. I bought a Marconi 2018 to use until I can figure out the 2040. Of course, I'm gonna use the 2018 but I still like the 2040.

That 2018 also showed me that Victore freq counter was off ass well.

Ok, so I emailed them and the reply I got was that they needed the holder style and load capacitance in order to make one.  SO.. this is where my ignorance will shine through, I don't know what the holder style is, I saw it somewhere but don't remember what site I was on when I was comparing them.  And I have no idea about the load capacitance... how might one find that out?

The two scopes I have now are by BK Precision, a 1474 and a 1474B.  Both of which I think are trash, I believe it'll take way too much work to get them back up and running and I really want something much newer, like what you're talking about.  So I'm thinking about tossing these two relics in the trash. 

BigMic919, don't be afraid to pop the lid off and look around.  Start testing some points in it and see what you get, it's possible it's something simple and easy to fix unless you need the same part I need... haha.

I hate to bring up an old thread but since there's only a few, I guess it's ok, haha.

I've got one of these also, checking the output on two different frequency counters, I see 27.183 on channel 19.  Well actually on the BK 1801 counter, I see 27.184 and on my Victor VC2000, I see the 27.813 reading.  I opened up the crystal oven to adjust the trimmer as per the service manual... well, made no difference and it looked kinda bad.  On the side of it is 8-60, that's the only number or markings on the piece, I figure it means 8pf on the lowest adjustment and 60pf on the highest.  So I ordered something very close from Digikey, it arrived today and I put it in as best I could (not the same exactly as what came out).  So I get the same exact adjustment ranges or frequency, still off by the same readings.

Those two crystals that are inside, the 10.240 and 10.243 mhz.  On the 10.243 crystal, using the oscillator built into the frequency counter I get 10241.457 kHz which is two off from what's marked on the part.  Which is also two off just like the frequency output of the generator.  Could this be the issue?

The 10.240 piece, I get 10239.657 or so... which is almost dead on for what's marked on the part.  Other than being slightly off frequency, it seems to work just fine and I only noticed it once I hooked up an inline freq counter on my bench.  I attempted to find one with Google, seems they don't exist any more, so where would I find a crystal to replace the 10.243 one with?
