[sdiy] Scope recommendations (again)

[Ralph Karsten]

Hi Julian,

You will find dual trace to be pretty important. for most analog stuff, 5MHz is plenty but for digital stuff you need more like 100MHz to see some of the goofy things that can go on. 

I just replaced one of my scopes with a new one. If you want the old one (dual trace Telequipment D61 10Mhz), I'd let it go for $20.00 plus the cost of shipping. It is set up for 117V, and I have no idea if it can be converted to 235V. I have no probes for it, but it does work OK- I used it just two weeks ago to see some diode rectifier buzz that I had to kill in an amplifier.

More info here about the D61:

Given how scopes like this go, the cost of shipping may be more then the unit is worth, so I would check locally too.

Good Luck,

-Ralph
