I've been adding to my collection over the past 2 years, focusing mainly on the 5xx and 7k series. There will always be a special place in my heart for the old tube scopes, and I enjoy shepherding them into their place in history. The 7k stuff is interesting to be because it was the gear I drooled over in catalogs some 25 years ago, and now I can afford it!
I feel the same way about the 2232. With apologies to Lester Burnham, it is the
oscilloscope I've always wanted and now I have it. I rule! I mostly use a 2230
though.
Collection highlights:
454A - Just fired 'er up after 20 years and I was unsurprised to see a clean accurate trace.
556 - It'll make it back onto the bench for a slow power-up and checkout one of these days.
551 - newer acquisition. Shows a trace but needs some love.
453 - my first 'apartment scope' works well other then B triggering.
My first real oscilloscope is a Lavoie LA-265A which is a clone of the Tektronix
545A. It has the Lavoie clone of the Tektronix CA amplifier.
I picked up a Tektronix 547 with a working 1A1 and a broken CA not long ago. It
just needs some general switch and potentiometer cleaning. The trace is much
better than my Lavoie but I have not used it enough to compare it to a later
Tektronix oscilloscope.
7834 - troubleshooting the readout board right now (U3433 is looking like the culprit)
7603 - newer acquisition, perfect host for my;
7D01 - recently rebuilt back info behaving
7D20 - works great, save a bad 4116 RAM (U410). It's on the list..
I have a pair of 7D01s with one DF1 and one DF2. I have not decided if they are
worth rebuilding for general use.
My 7603 was my first 7000 series oscilloscope and works better every time I use
it.
I have one 7834 with a damaged CRT that has geometry problems (I think UPS
dropped it.) and another 7834 with a burnt but completely usable CRT. I decided
that the 7834 was the cheapest way to get a high bandwidth variable persistence
storage oscilloscope.
I picked up a 7CT1N that came packaged in a 7904 and have grown to really like
the mainframe for its bright and clear CRT. This one got mistreated by UPS also
damaging the calibrator control which sticks out but I fixed it.
At some point I plan on rebuilding all of my 4 bay 7000 series power supplies by
replacing capacitors and zener diodes. A couple of them occasionally tick at
startup or sometimes when operating.
