Hi Dennis. I’d be glad to pass on to Peter my thoughts about 500 series scopes. I have a nearly pristine 555 on a Tek scope cart, and have a few plugins ( CA (2), D, W, and a 1A7 I purchased from Stan

Hi all: Yes....not Tek, but wondering if someone has info on this. I have a Dranetz 3100 Sampling Network Analyzer. If you google its stablemate the 3105, the 3100 is close, but does not possess the c

Hi everyone. I’ve got a 7633 which I purchased having a red surplus tag on it stating “short trace”. Knowing the reduced scan mode, I suspected that someone had tested it in that mode and surplussed i

Just to chime in. I got a 555 some years back with 2 CA, and a D. I have since added a W, and 1A7. I’ll not mention the initial price, as it was phenomenal. The crt has the purple/blue phosphor for ph

Hi Ernesto. As a happy 555 owner (beautiful sharp blue trace (p13 phosphor?). Re washing, check the BAMA (Boat Anchor ....) and look in the tek section for tektronix magazines....or maybe I am thinkin

Do you happen to have the horizontal board? My 7633 has flaky horizontal ( short trace) which I fixed, but recently went to No trace.

Hi Tim: Rickreall hamfest....wow.....I lived not far from there growing up. Now live further north in Washington state. I happen to have 4 Tek scopes: 7834, 7633, 7623, and a fine 555 ( with 2 CAs, D,
