Re: Tek Type 516 Restoration

It always confuses me to hear these guys who have systems that are so close to perfection then say they changed something and 'it opens up the music in ways I never heard before’. WTF? Either your system is so close to perfect that there’s almost no improvement left to be had, or you’re delusional....

Re: Tek Type 516 Restoration

Those are ECC86/6GM8 which I'm sure the phools lust after. Oddly all the 6DJ8's in this scope are GE branded and USA made so they have almost no appeal to the phools. But it does have a somewhat uncommon ECC82/12AU7 Bugle Boy which could bring big bucks. Might be tempting to put them up for sale at...

Re: Post a picture of a cat

Seen lots of cats today, some mangy.

Started off the day by walking 50 yards to the fishmarket, followed by breakfast of a freshly filleted fish (still with rigor mortis) fried in butter and freshly cooked shrimp stock.

Later will visit the dragons' home in Meereen.

Re: Tektronix 465B repair

Everybody needs a 485 for its 50ohm input. Helps if the user can do mental arithmetic, rather than relying on cursor readout :) I happen to prefer my 2465CTS with 50Ω input and cursors with readouts, including a frequency counter... :D I think you'll find it is 50ohm//20pF => the usual crap VSWR.

Re: Tektronix 465B repair

Thanks for the offer. I'm contemplating what to do at the moment and will let you know. The outcome is one of: 1) Go argh and wonder why I bought another 465B 2) Accept your gracious offer 3) Buy all the 465B's that come up on eBay and surround myself with a wall of scopes. Go with choice three, bu...
