If you can get to all of it, a pencil eraser actually works pretty well. It would be tougher to get around the base, though.

I just received a 2465b and it seemed fine on my initial check. However, after leaving it on for several minutes, the readout and display started to drift up and down. At times, the top of the readout

Good point! ?I wasn't really thinking. ?They likely are mostly silver since they tarnished black. ?Nickel will probably go greenish (or perhaps that's from the copper underneath that oxidize on a

Hi Dan. On all the TE I have, the connectors appear to be Silver plated. You could (!) carefully clean them with "Tarnex" liquid. Then clean off that stuff with Windex, etc. Most of the time, I simply

Hi folks, ? I am sure this has been asked before, so please point me to the correct links if so. ?A quick search of the archives didn't find anything easily. ? How does one clean the nickel-plated

Very nice!

Thanks for that Mark. Another tool in the box. Dave Sent from my iPhone

I have these almost since they were new and now need to find a good home for them both. The tubes are good nice sharp traces, but the 585 needs a HV cap replaced, and the 535 is slow to warm up..I

I would be happy just for some power good L.E.D,S and maybe test points for the transistors. Regards Dave

Hi Chris, You are almost there. Pl read page 3-45 which explains how the circuit operates. Put the large 87 volts schematic in front of you. Look at resistor R1228 and R1227. Check that they are

Ok, I replaced Q1221, Q1222 and Q1223. I also verified R1212 while I had it out. Still no go - I tested all 3 transistors with my DMM and they all look like they're good. Where do I go from here?

==================== Which One? There are three: ? The 1st one Tek made has no Tek part number on it but it does say on the front panel: High Amplitude Pulse Generator. This unit has a Step

Ah, I didn't realize they were that similar; I was interested in the first one (no part number). -Dave

PG505 ( 80V) and the 106 ( >120V unterminated) pulsegenerator are both also high amplitude pulsegenerators. Fred PA4TIM

Which One? There are three: · The 1st one Tek made has no Tek part number on it but it does say on the front panel: High Amplitude Pulse Generator. This unit has a Step Attenuator, Variable Amplitude

Just wondering if a manual/schematic is "out there" for the Tek High Amplitude Pulse Generator. -Dave _,_._,___
