Opinions on brands of OLD scopes

[G0HZU]

My favourite scope is the classic Tek 465 but it does suffer a bit of fan noise and some may find this tiring or distracting in an otherwise quiet workroom.

I think you need a new fan... my 465b fan is whisper quiet.

My 465 is quiet also.  Original fan.  Bought it at a swap meet a few years ago for $125  from an older tech that repaired and calibrated them for a living. It's got the DM44 option (digital meter) also.

I've used quite a few 465s and mine is a typical example I believe. Besides, 'whisper quiet' is open to interpretation as is my description of 'distracting'.
To put this in perspective, the fan in my 465 is a LOT quieter than the little fan in my Marconi 2024 signal generator which is why I prefer to use my 2019 signal generators as much as possible. They have no fans

If the scope is the only thing in the room making a noise then it can be distracting to me over time. I have the same issues with laptop HDDs and hate any kind of laptop that makes a noise when running whilst I am trying to concentrate. I'm sure I'm not alone in this

I've got a Tek 485 laying around collecting dust.  I also just pulled 2 Tek 7633's off the bench to make room for a Rigol DS2072 arriving tomorrow .  The 485 works well except the top 3 fastest sweep speeds (5,2,1 ns) don't work correctly.  Paid $50 for it DOA.  Replaced a hand full of tantalum caps, a couple of transistors and several diodes.  I probably have about $60 in it.  I'd be happy to help out a fellow EEV Blog member and sell it for the $60 I have in it + whatever shipping thru a UPS Store ends up being.  Double boxed it will probably be $40-50.

I have around $85 in one of the 7633's so I'd let it go for that (without plug-ins).  Everything works (not sure about the storage system - never used it).  But with shipping and plugins, you'd probably be over $200.

Sorry, no extra probes laying around .

Let me know if you're interested.
