549 on Detroit Craigslist

Not related, but looks decent for a reasonable price. It's been on and off the
list for a bit and now has a lower price.

Paul,
I guess there is no premium for all the dust! (Seems to me that 20 minutes with windex and paper towels and a toothbrush would make it way more attractive!)
I wonder if the 549 is the storage version of the 547. Not too long ago I got a 547 to replace one that was lost in a disaster. It seems to work well, though I have not had a chance to get used to it yet. (One channel of the 1A1 preamp shows the wrong gain.)
Years ago, I did have a couple of 561 scopes that I used a lot, and a 564 storage version also. Maybe the 549 is the same sort of storage version of the 547.
Long live these beasts!

Ho Roy,
It's not as fast as the 547, probably more like a storage version of the 545. I used one for a while until I found a 547. It's a great performer but can have the HV transformer thermal runaway problem and the CRT is completely ireplaceable and prone to deterioration of the storage function and screen burns. The vertical output tubes are 8608s that are very hard to replace.
Bottom line, if the CRT and vertical amp are working properly then the HV transformer is worth rewinding and it's a useable scope.
Hopefully it will be saved from the tube scavengers.

I am sorely tempted, but I have too many projects right now and I have
to downsize in the near future as well.
Looks like a 1A4 plugin in it as well.
If someone is interested, I could pick it up and hold it for a while.
Shipping is getting out of hand these days, so you'd have to be
within driving distance.

A 549 was my first ‘serious’ ‘scope, back in the 70’s (if you discount a Solartron CD1400 that I was given while working at Ferranti!) It was utterly reliable, big and impressive and a good heater for my ‘lab’ at the time - my bedroom! Yes, that does look like a 1A4, very useful! If you have the space, go for it!
