I have a type 585 oscope how much is it worth

Hi Don?t sell him over eBay and other plattform, because audio people will killing them for 6DJ8. In Germany are selling many 585 to this idiots. You can pull out 6Dj8, put russia 6922 into 585. You will seeing, interested buyer will be reduced, because some are a tube vulture ;-) Regards matt |

I overheard a guy at the DeAnza flea market a few years ago tell about how he would wipe the markings off tubes and remark with a marker so the hard core tube vultures wouldn't want the scopes/tubes he was selling, but the people who would actually use the scopes wouldn't care. Seemed kind of extreme... -Dave From: "mattko87" To: TekScopes@... Sent: Monday, July 9, 2012 9:20:32 PM Subject: [TekScopes] Re: I have a type 585 oscope how much is it worth ?

Trouble is that a 585 has almost no monetary value. Unless you manage to find someone local who can appreciate an 80mHz tube scope with 4 cm deflection you probably can't give it away. Wouldn't it be better to see it parted out than crushed and buried? I don't sacrifice equipment for audio tubes but in a case like this, recycling tubes can be the best practicable outcome…sad but true. Sent from my Verizon Wireless Phone -----Original message-----

585, 581 are a epic technologiy. high bandwith, distributed deflection and tunneldiode -base triggering (only with A-version) [url][/url] Picture of T581 CRT, 骋谤ü蝉蝉 Matt --- In TekScopes@..., jerry massengale <j_massengale@...> wrote:

No argument; epic but nearly useless because of only 4 cm vertical deflection. I am preserving two 585As with all five plug-ins ever made for it, including the cal unit and both versions of the 81 adapter. The seller made me buy them to get my hands on some 547s I wanted. Guess he was expecting to get stuck with them and having to live with his only other option… Gladly took them and will pick up all in driving range - but I'll probably never use any of them (contrary to other models; 547, 556, 561, 565, 503…). FYI am in Northern California and will travel to rescue all I can. Bernd Schroder Sent from my Verizon Wireless Phone -----Original message-----

开云体育Hi all,I am also in Germany, and have a 585 and a 585A (and some more....), and I will gladly drive some distance to give a good home to anoter of these very fine instruments. Of course, I also wouldn't decline a 547, 549, 555, (add some here!) I like to restore these great instruments, and the 585 (A) was the best you could buy for money at the time of its production. Think of it as a great car that is 50 years old: "Power nothing", an american used to describe these cars, but they are still loved oldtimers. I also think so about electronics.

I'd like to thank Casey for posting here; at least there's a fighting chance somebody with the proper inclination and skill will see it AND lives close enough to adopt it. Google says Scotts Mills is about an hour from the "mothership" (Beaverton), so I suppose there's hope.

Modern DSO have many noise. Old CRT-o?scope can more resolution. But: Only one fun, that also big street cruiser with babbling V8. Regrads Matt --- In TekScopes@..., "tubesnthings@..."<tubesnthings@...> wrote:

IMO, Tunnel diode trigging in the A models is a VERY IMPORTANT difference. The non-A's only triggered at a tiny fraction of their BW rating. Not much of a fan of 4 division vertical as well. The 545 and 545A shared this same trait. Lots of BW for the time, but at an expense. The design is interesting for its day, but I don't find them too useful as working scopes. - Steve |

There are many reasons a person might value a scope. When a person cares about the beauty of an instrument and what it represents historically, its utility as an oscilloscope for everyday use becomes a secondary factor, if a factor at all.

Also, a lot of interesting concepts are embodied in old scopes. For example, distributed amplifiers, equivalent-time analog sampling, tunnel diode triggering, and storage CRTs. These things tickle my mind. I own some scopes just so I can marvel at them. Basically, they are Faberge eggs for an electronics enthusiast. That said, I do like to bring my old scopes into proper calibration. Sometimes a decision has to be made, whether to functionally restore or just clean up a scope. Historic integrity is likely to be lost in a functional restoration of an early Tek scope. It is a tough decision. I have no rigid position on the issue. -Kurt For example, I recently got a 514. I'm pretty sure that I'd need to do extensive replacement of internal parts to get it working properly. It is never clear what's the right thing to do in this situation and every person has to make their own decision. For the 514, I'm going to leave it alone. Other times, I couldn't resist the urge to do functional restoration. My 567 was just too interesting not to repair. So I replaced the electrolytics and got it fully operational. I wouldn't blame somebody if they chose, in the same situation, to leave the scope unmolested. --- In TekScopes@..., "Steve" <ditter2@...> wrote:

series I have chosen for now as my particular expression of the thoughts below. Tis why I enjoy this forum so much. Regardless of the specific cup of tea people choose to quench the thirst (ok corny metaphor but what the heck I am an Chem E after all not a poet). Bravo Kurt. -----Original Message-----
