I found this baby in a nice Tek box among the Tek spares I recently bought from europe. Took a while to find data on it, it is a small gold pellet tunnel diode, the RPR does not say what it is used in

Several years ago I bought a PG506 (B40000 and up) along with other TM500 plug ins. I was unlucky enough to damage the PG506 by installing it in a TM506 that had a bad pass transistor. For whatever re

I need your help: I am a newcomer- all power rails are ok, but the tube heating has only 1.2 Volt? I have no idea? Regards and thank you, Manfred

Happy Easter everyone, my 492P was working when error 59 and then error 58 appeared for a moment on the screen, at the same time on all span / div the signal amplitude is low compared to the correct v

Hi, Anyone happen to know if there are dimensional drawings for the 560 series plugins floating about? I'm thinking about taking a stab at modelling a 3D printed plugin protector/container. Yeah, obvi

Does anyone know what this is from? JAN CNU 5CPI 5 inch display two foot long CRT NOS in box Free to a good home Wally

I have a 1730 waveform monitor that has fried the transistor that drives the high voltage transformer. A malfunction in the CRT bias circuit caused the beam current to go too high and fry the transist

I'm planning to add a readout board to a 7603 Option 1, but I don't have the cables to connect the readout board to the rest of the scope. Those cables all have Peltola connectors on at least one end,

from Tim P (UK) I have a bunch of S1 and S2 sampler heads, along with two 3S2 plug-ins. I am trying to sort out what head works with which plug-in, ideally to get them all to work with each other. The

Hi All, I picked up a 7934 this past weekend, and I tried to power it up today. Sadly as soon as the panel lit up, it went out. Checked the main fuse, and sure enough it was out. I pulled down the man

I rescued a nice looking B&K CRT tube tester. Model 465 Has the manual and the connectors also. From TV repair guy. I do not know if it can test scope tubes or not,so I thought I would ask here first.

In Kenilworth UK. I have available: 2 x 154-0721-00 7633 CRTs believed good but HV PSUs failed within 5 minutes of power on (I think damp in the transformer) so I wasn't able to test much. 2 x 7633 ma

Hello everyone I'm haunted by phase lock failures. When I select span / div at 50 kHz or lower the signal on the screen does not stand still and hops from left to right. I also noticed that the noise

I've never used this special low-temp solder to remove SMD IC's. I 'm game to try it. Here is Mouser's inventory. Exactly which one is the correct low-temp solder? https://www.mouser.co.il/Chip-Quik/T

Greetings everyone, I have a question to ask you: with a Tektronix 492AP spectrum analyzer connected to the PC via the Prologix GP-IB to USB adapter and launching the HP 7470A emulator program on the

For about 15€ I bought this 465 for parts. Seller said it didn’t turn on at all. I opened it up, and indeed, it definitely can’t function. There are apparently 4 missing components in the power supply

I bought my 2246 on eBay 6 years ago. It was really good until 8 weeks ago. Then, without warning, one day it wouldn't turn at all - no diagnostic LEDs, no clicking, nothing. I found out the hard way

My Tektronix 465 has a -8vdc power supply problem. The voltage is -2.6vdc. All the other power supply voltages ae correct. I need to be able to isolate the circuits as best I can when the correct comp

I have a 7L14 in excellent shape for sale. If interested, I can send pictures of the unit operating. I have not used it much in the last 8 years, but it works well. I will consider offers , but reserv
