Thank you for that information. That means that we can add the 666 to Dennis' list of tube testers that will work with his VCTC. DaveD KC0WJN [email protected]> wrote:

Dave, The difference between the Eico 666 and 667 was purely to update the types of tubes tested: the 667 added support for 9 pin Novar and 12 pin Compactron tubes, and dropped the sockets for large

Finally I decided to take care of the baby, before is too late: TEK2465B S/N: B017389 Hours: 10045 Pwer On/Off: 1783 AFAIK never recalibrated, no sticker applied Apparently I have at leasr OPTION 5

Jon, I have 2 SC504. Both of these units have this exact mod. I found some documentation that stated that a later crt required a circuit mod. Thanks, still putting the pieces together. Barry

The power supply on a 2465 has 2 four pin connectors to power optional Lemo jacks on the rear panel of the 2465. No new power supply needed, just a jack, board connector, hole and some wire.

Hi, I have VmtWin-release032201.zip and some more. Try this: https://1drv.ms/u/c/3c3521628e6cc41e/ER7EbI5iITUggDyNrQAAAAAB5zjM6oyIZLmIAsPv4t1dyA?e=lEACjo My VM700T backup battery did run out, and I

Thanks, I'll look at that. Andy.

Hello Jose, the one you are mentioning is not right schematic for TDS784A power supply. Here you can find proper diagram: https://hakanh.com/dl/docs/hardtofind/TDS544A_A17-A19(PS).pdf Power supply

OK, found one good enough: https://download.tek.com/manual/070971003.pdf page 5-141

I'm assuming a similar setup like the later 492 for the following comments... The issue seems to be one of accuracy. It won't lock in time when high accuracy is demanded by the cpu. If like the 492

Good Morning All: Got a 784A where the PSU is bad (this model: https://jvgavila.com/tds524a_6.jpg) one of the capacitors has leaked and may be exploded to the point where the fiber glass weaving of

I think you should probably review what was done with the EHT transformer replacement. My guess is its running unregulated and the output is way too high. That would cause reduced horizontal and

The bus,wire is,perhaps an indicator of a mod,perhaps b y previous repair attempt. Suggest you Remove the Trim pot see the,original PCB. Jon

GM all - Someone from the list has responded to my plea for assistance and I have a couple of the required connectors on the way. Cheers, Bill

GM Clark - Buying a 1101A would definitely be more practical but building stuff is fun. It is, after all, why i have all this gear in the first place. If I fail, the 1101A is the fallback option

Does anyone have a copy of the “REV B” manual? If so, does the HV board show a trimmer? Many thanks!

Anybody know how close the 2755 is to the earlier 492b ... 494a series design?

Hey there, Do you have a name we could call you by? The most common problem by far with the 24X5B scopes is a bad DAC reference due to electrolyte leakage from the SMD caps on the A5 board. The
