Buying an oscilloscope

[Arpit]

I was building an inverter, and started getting anomalies. I realised
that I really should have a look at the output waveform. I assume to
do this I'll need an oscilloscope, but they are very expensive new and
I certainly can't afford one.
Oatley electronics sells some cheap

ZC0339 30MHz, Dual trace. Two units included. One has faulty vertical
amplifiers and the other has noisy pots. (1 pair only) $330

--------------------------------------------------------------------------------
ZC0340 (USED) HITACHI 60MHz OSCILLOSCOPE: Model# V-650F. Faulty
Attenuator controls. (1 only) $150

--------------------------------------------------------------------------------
ZC0341 (USED) LEADER 35MHZ OSCILLOSCOPE: Model# LBO 524a. Two units
included. One has faulty vertical Amplifiers and the other has a noisy
CH2. (1 pair only) $300

But they are all faulty. Would the faults be easy to repair? IF not,
would there be some place where oscilloscopes go cheap?

Why not look in the trading post?

There are lots of CROs on ebay.

There are lots of CROs on ebay.

I've got one for sale, email me for details.
Won't be able to get back to you till tomorrow though.

**I am looking to sell my BWD 521, dual beam (Not dual trace) CRO. I seem to
recall it is 40MHz (maybe 60MHz). I'll check tomorrow. It comes with a
money-back guarantee, a full instruction manual/schematics and a brand new,
spare tube. It's a big old fella, but all the bits are bog standard and it's
pretty easy to work on, if you ever need to.

$350.00.

There should be plenty on eBay
Macservice in Melbourne sell plenty of reconditioned ones that way.
A very basic 15-20MHz one should do you fine, they can be had fully
working for under $200.

Yep, I bought a reconditioned HP184 Dual trace 100MHz Storage CRO from
Macservice for $250 off ebay. It's a really old CRO, probably 30 years
old, but I used to use one when I was an electronics tech years ago,
and it proved to be bullet proof.

I've had this one for a year now, and it hasn't missed a beat.
