Hi, recently my DSA602, due to power supply shutdown, required 3 attempts to start up successfully. Some minutes later it had a short power-out during operation that made the user interface stall. A

Hi all As I might have mentioned I have another sick 2445, this time probably U800 as no horizontal deflection (but I *might* have a U800 in one of the parts 'scopes I also still have). Anyway,

Jean-Paul, I agree. I think its best to live with a 3db loss than finding the right connector to buy! Thanks.

Yeah, I read the same. Butane has a similar vapor pressure to Freon so it apparently works well, up to and in excess of the working voltage of the probe. However, the flammability is a

I didn't notice much residue on the valves but I do notice that they're made of a white material and the replacements I'm seeing are clear. That might not indicate anything unordinary but I'm

Thanks, Dave. It's not binding, but seems to be hitting something on the way out. I'll keep at it, but let me know if something jogs your memory :)

Download the manual and buy some filters for it. Running any desoldering station designed with filters without those filters will cause clogging and eventually damage. Disassemble and clean it

Modifying front panel connectors is a difficult mod. The oddball résultats degrades swapping or resales value. A $20..30 Mini-Circuits,or DIY min loss pad is much easier solution. 3db loss is

It's looking like a 5V S/C to pin-2 of the 4053. Isolating the A1 completely shows a +5V pull-up even though there are no components anywhere along that REF1 rail other than the 4053. I have got to

Jared, I thought I had read somewhere that you could fill the body of a P6015 with butane. I don't know if it gives the same dielectric properties, and, of course, it's flammable. I assume that you

While I have a number of RM scopes, I don't have a 585A; however, it doesn't take much to jam up the works. Rail hardware mounted incorrectly, a replaced screw of the wrong length, random junk

I too have a 3S76/3T77 (non-A) combo that I'll soon be tackling. I'd mentioned here before that I'm working on a 564, and some may recall I was looking for extenders. I now have a pair of extenders,

Yeah, it would be great to find out what oil is used by Tek in the P6015A, but they seem to be a bit tight-lipped about it...

Jared: Interesting idea. It is still possible to obtain Freon dependng on your location. Beware that the gas seals and design of P6015 may not be compatible to some silicon iols and that there are

My probe seems to work ok, but being the earlier model it needs the unobtanium Freon to work at it's full specs, so I was thinking of filling it with silicon oil like the A model, but that changes the

You folks think I am a pain now, wait till I start pestering you for advice and guidance on my other Tek gear in the queue. Have a dead Type 114 and Type 106, and things will get really exciting when

Took your advice to heart Dave, left some select capacitors in circuit, but replaced with the originals a few of the bypass caps. Will report more tomorrow. Thank you, and yes, all this helps.

I have encountered this with other scopes, both a 2465 and a 475, both of which had dents in the corner of the outer metal case. When the rear plate reached the dent the case stopped sliding, hard!

Try cleaning the vaporized flux residue from the valves on the pump. Cleaning the flux from the carbon vanes in my Pace desoldering station has fixed a low vacuum problem. Glenn

I've decided to resurrect my used Hakko 470 so I can do some better desoldering on my Tek and other boards. After cleaning the hole through the heating element and ensuring the rest of the
