Just finished my DAC (1541A) , but 無聲出. Need Help!!!

BongCalifornia,

You are so lucky to own a vintage Tek 465B scope. May I know how can get an analog Tek scope such as 2445 cheap but without risk?

Hi, alfcat,

I breed the female BSH as shown. She won lots of prizes in cat show.

May I know where to buy a trusty analog Tek scope in Hong Kong. I also search on ebay for a 2445 150MHz 4ch scope. But the shipping charge cost as much as the scope. I had been 2nd hand test eqiup shop in KwunTong and Mongkwok. They told me some Tek scopes are broken and they sell it "as is" even at HK$10,000. I wondor I could get a Tek analog scope in good condition at a fair price in local.

My cats at a glance. Some of them have their new homes in Hong Kong, US, Australia, Malaysia, Canada. They are all the stars in cat shows.

Hi alfcat,

Oh I see, I think I have more confidence on buying Tek analog scope on ebay now. Just be patient on looking for any Hong Kong sellers.

Thanks for your advice ....

But I also notice the vintage Tek analog scope is being more and more expensive now. Just like the fine and rare of Bordeaux .....

Dear alfcat,

Similar to hifi audio, breeding cat is only my hobby. However the adoption charge can cover the expense of attending shows.

Thanks for your help on my Tektronix analog scope searching. I will keep my eyes open on ebay once the Hong Kong seller surface.

You know the Tek 465 is the last scope they made using standard IC, which is maintainable lifetime, even including the CRT. For the analog scope mft after the 465, Tek used custom IC that the scope can be serviced as long as old stock custom IC last. Once broken, all finished.

Dear alfcat,

Thanks for your help.

All guys pursue old Tek analog scopes because only analog scopes tell the truth. The component datasheet only shows waveform photos taken from analog scope, but not using data captured by digital scope. The Aliasing Error in digital scope limit the accuracy of high frequency information when in slow time-base. This was my past experience.

Thanks a lot. I will check within these days.
