Hi, I have Service Manuals for 465, 465B and 466 scopes. The 465 and 466 would appear to have pretty much the same fan motor and circuit. The circuit number for the fan motor is B1690 in both cases,

You should check the parts lists just to be sure however the 464 and 466 are part of the 465 group. One thing I have not been able to track down however is the variations of the 465 if there were

Dennis, On this page: http://www.electrojumble.org/Valves_etc.htm Item VH924 is an interesting item with a B7G plug and a Noval socket. Reasonable price, too. Colin. Sent: 28 March 2017

Given the image shows a part that's used, I assume RFE means"Removed From Equipment". Thanks, Barry - N4BUQ

Hi, I've made this query wide-ranging, but it should become obvious why. I have a 468 DSO which I am trying to calibrate. It is a bit of a nuisance that the Volts/Div knob on Channel 2 has some

Leeds lists them but not sure if they're stocked. If you follow the "+" link beside this entry at http://www.leedsradio.com/parts-sockets.html 7 pin minature plug - fits sockets for 1L6, 6AU6 etc

Hi Colin, 9-pin socket savers are available from every tube site I have checked. They are even available direct from the manufacturers via Alibaba. The ones that are impossible to find are the 7-pin.

Hey all, sorry to revive this thread, but quick follow up question regarding similar models... Are the 465 and 466 close enough in terms of parts that I might be able to part a 465 (particularly the

Dennis, Is this any good to you? http://www.tubeampdoctor.com/en/shop_Tube_sockets_and_Accessories_9_PIN_tube _socket/Novalplug_Noval_tube_base_adapter_2163 The price seems reasonable. Colin.

Yeah. I think they're likey "usable-old-stock". (Hence my not really a source comment) I dont think anyone is making anything new besides the 8 pin octal and 9 pin ones everyone

For jobs like this, I use my largest soldering iron tip for its high heat capacity. Soldering then takes just a second or two; the large surface area transfers a lot of heat rapidly and the large

The driver hybrid on the 7000 series vertical output amplifiers have a pressed connection to the top of the metal can package which goes to ground. It is held in place with a plastic clip instead of

Thank you all for advice on my 2456 u800.155-0241-01/-02/-00 are they all the same ?Or do I need faster chip for 2465/2465b? Thanksmoe mm0mrmSent from Yahoo Mail on Android [Non-text portions of

Hi, I don't think this should be of any problem. The die itself is attached to the bottom of the IC, not the to of the case where you'll solder it. If you are worried, put the IC on some cooling,

Hi Dave, Thank you for your offer but for the moment I think I have a better solution. The pins coming out of a tube base are about 1/4" (6.8mm). If I try to push a longer pin into a tube socket it

Hi David, He has a 7-pin socket saver listed for $25. You are right about him not being cheap. Thanks for the link. Dennis Tillman W7PF

Hi Fabio, I have two 466s, an early and a late model, and both have the grounding strap soldered to the output amp if I remember correctly. However, I doubt it really matters as the hybrid has a

I have an early 464 manual that shows a braid on the VOA, just across the device. I have two 466 manuals, one earlier and one later that also show the 464's(!) VOA. Neither shows a

Maybe use one of those modern CPU heatsinks, like this? http://www.legitreviews.com/images/reviews/1303/rolimatech-Armageddon-Front2.jpg This one's respectable:

I wouldn't call it a proper "source", but the last 7-pin socket saver I got was from Jim Cross @ http://vacuumtubesinc.com I had to send him a note specifically for it, and he scrounged a reasonable
