Tektronix 2225

[echen1024]

I have a chance to purchase a broken Tektronix 2225 for $40 + $33 shipping. Should I go for it? The seller says there is a broken vertical board, and he purchased a replacement but doesn't know how to install it.

Do you have the equipment to calibrate it? Look at the service manual what do you need.

Yes I do...

Go for it I say. I bought the same one for 130 USD (with shipping) and haven't regretted it. It is a good reliable piece of equipment. The biggest problem you will encounter is taking of the knobs, if it wasn't serviced lately. (I know mine was a pain to take apart)

Good. You should do a full adjustment after a board swap.

But i don't think it's a good deal. I would not pay more than 20-25% of which i would pay for a working one. The 2225 is a very basic scope.

And the replacement board could be damaged. IMHO 10-20$ with shipping would be ok.

Ok. So basically, the selling price is still a bit high? I know that 2225 prices have skyrocketed after Dave did a video on them.

Yes, the selling price is too high. It's broken. And I would place the 2225 a bit over the 20MHz  <=50$ class. Why do you want a 2225?

I just wanted a cheap analog scope, and love old Tek gear.

Ok. Tektronix aren't usually cheap. But i would look for one with dual timebase. That's the main shortcoming of the 2225 IMHO.
