Chuck comments reminded me that I forgot to mention one other intriguing possibility since you have a 7104: Get yourself a 519. This was the original, and first ever, 1GHz scope Tek made. It make a

Members interested in Chris probes please contact him OFF LIST at cwilkson@.... This will keep the noise level down on the forum. Dennis Tillman W7PF

Hi Chris, In the future please clearly state in a place that is hard to miss: CONTACT ME OFF LIST IF YOU ARE INTERESTED BUYING MY PROBES. Otherwise we get people replying to the list which clogs the

If you want heat, the 547 is a poor choice, being mostly solid state. Better would be a 535, 535A, 545, 545A, 585, or 585A. Nice long vacuum tube distributed vertical amplifiers... If you are a true

I would like the Elenco probe 73 Richard W4MCD

Hi Sean, The 547 is a beautiful scope and it marked the transition to semiconductors at Tek. It is easily my favorite in the 500 series. But there is another scope to consider. Have you considered the

Hi Alberto, I actually got it working (was a dumb short to the chassis caused by that resistor under the fan), but I'd be interested in seeing your numbers just as a data point for future reference.

Or someone at the auction preview decided to monkey with it, knowing it would cause a short and make it seem like the scope is dead. Either way, it's working now. Sean

Hi all, Getting the 7104 has gotten me thinking again, I've always wanted one nice example of a classic 5xx series scope. Ideally in good shape, so I can use it as a lab heater in the winter. :o) I'm

It seems however that the 7A26 change is from -05 to -07 at S/N B208880. Jim Ford mentions a 20 pF plugin B19xxxx and a 22 pF plugin B21xxxx. I have S/N B198122 and B171610, both 20 pF and board

Dale's post reminded me that I neglected to mention that GR made many laboratory standard capacitors, inductors, resistors, and other things. As Dale pointed out so well their instruments are still in

Nigel, I _do_ have one of these, but are you aware that they are also available, new and used, from Qservice for $US 7.98/$US 6.50? For orders below 40.00$ shipping is flat 9.00 USD to all

I'm after 3 of these Nigel but would take a couple more to 'make it happen'?! Jonathan

Any chance anybody in the UK has a spare one of these? I can buy some from the US at a reasonable price on eBay but the postage and import charges at both ends plus UK Post Office "handling" fees make

When in doubt just ask the seller selling the adapter board, they will see if they can make a version of this board that accepts snap on capacitors

Article in WW from Dec 79: // 7A16A, 7A26 INPUT CAPACITANCE INCREASE Reference: 7A16A S/N B010100 - B099999 (If 050 Kit installed) 7A16A S/N Bl00000 & Up 7A26 S/N B010100 - B119999 (If 050 Kit

Because I own a number of GR instruments that use 874 output connectors I have many 874 cables as well as many GR between-series adapters to adapt 874 to BNC, N, PL-259/SO-239, and a few others. --

Dennis is correct. The oldest GR instrument in use on my bench is a Type1231-B Amplifier and Null Detector and its accessory Type 1231-P2 Tuned Circuit, both ca. 1950 (my 1231-B is the early design).

Dear all, A couple of months ago, I obtained a CSA803A. When searching the internet and this Tek forum about CSA803X and 11801X scopes, I came across several messages related to the A5 Timing Board
