Hi there, This might be a bit offtopic since I'm bringing Telequipment scopes to discussion. But then again Telequipment was bought by Tektronix in the late 60's I think, so I hope all is well :-) As

Hello Andrew, Thank you for the reply from early May providing me with the TAS 465 service manual part number. I'm still trying to locate one (though it turns out my next door neighbor designed the ho

Hi, I've got a R564B rack mount storage CRO with a blown transistor in the power supply, not sure what other problems. I think the tube's OK. I have the schematic for a 564 low voltage and high voltag

Hiya Don and all the others, I've been checking a few things here and there and indeed re the D43, there is no +B reaching the vert amps. One of the sections in between caps (i.e. power supply filter

Problem is the manual I have is for a 5103N D11/D15. I have r242 as 22k, r101 as 100, r251 as 5.6, r239 as 100, r274 as 1m, and r213 as 62k. Need to know if these are listed as the same for a D10 5103
