Sorry that my email reply meant for Andrew in Sydney went out to the group. I didn't check the reply address before I hit the send button (and I also didn't correct the subject title). It's kinda

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

Hi Fernando, Check the power supplies in the D43. It sounds like something common to both the deflection circuits and beam voltages. It seems the horizontal circuits are working

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

Interesting range of opinions thus far.. and *yes* there's a relationship to scopes in all of this, IMhO. At least re test equipment operation, there are physics-laws + state of the 'mensuration art'

Hello, I'd agree with both Stan and Dean. If you want to meet the specs spelled out in the manual, then you should go by the manual. But I and many others the ballpark estimate is good enough.

Hello, Perhaps a change in subject is would be good right now. I caught up on the topics because I recently signed up. Anyway did you check the horizontal plates for jitter ? Because I had a

"guitar amps sound different with different sets of tubes from different manufacturers. Damned if I know why, but they do. Sometimes radically different. I almost feel that I have a split personality

It isn't human dynamic range or bandwidth that creates this demand for certain devices/brands Dean; it's a tone; a certain character of sound quality. There is no technical definition for this

Well hang on guys. I'm with you to a point. My original response was mainly ridiculing the hype and component pricing that is the consequence of that hype, within the audio community. I am not an

Relax Steve. A bit of humor, venting and off-topic chat is something fairly foreign to a group of mostly serious stodgy engineer/techies (sorry guys) that are interested in oscilloscopes. This sort

Ah yes, audio mumbo-jumbo. Before everyone jumps on my case, I do a fair amount of audio design and I DO know what i am talking about. Most people forget there is a way to get very close to 'what
