Hi, I am working on a new GS35B HF amp design. Some questions: -I would like to buy some sockets instead of machining them myself. Could you gentlemen direct me to a person selling sockets that norma
OK, thanks. Will consider a interlock between the racks as well as a separate ground strip between the racks. Will probably have to isolate the Bminus and therefore the casing of the HV connector (if
SHV connectors look like a good candidate. This reference http://en.wikipedia.org/wiki/SHV_connector describes what I am looking for: center pin is engaged after the casing is engaged. Center pin is
Yes, that is an option. However if someone accidentically removes Bminus connector before Bplus connector and the interchassis ground strip has been disconnected or has a bad connection, the whole RF
Good idea to use diodes instead of drop resistor Bill. Thank you for helping out! I would think that the diodes should be able to withstand very large surges, as you mention in case of a glitch. If t
I am thinking about making my GS35B amp project autotune. A microprosessor circuit will remember the correct tune settings for each band (C1, L, C2) and when I switch bands the amp will tune itselves
Hi. I have been following the interesting safety discussion. Let us consider this scenario: we have a separate amp and HV deck. The anode has a potential of 3650 volts on it. The cap bank in the HV d
Hi, thank you for your responses: OK Carl. Thanks for confirming my analysis. I will definately take this into consideration in my current / next amp designs. == OK Bill, will look into using clampin
Question to the machinists on this list: I am considering doing some basic sheet metal bending/braking for making the PSU and RF deck cabinets on my GS35B linear from scratch. I have seen the nice wo
I have found that the Radiall SHV part number R317072000 for 50 ohm coax with crimp connection is speced and tested to 12kV (Note: when mated, not when unmated). The spec is signed but not verified.
Thank you for this good link Samir. Looks like K3IWK is specialising in just cabinet work. Only problem is that I am located in Europe, but flat packed kits may perhaps be possible to send. The shipp
Hi Steve, I guess they underspec. the cable intentionally to not get a bunch of lawyers on their back in case it arcs over and causes damage. However, the time in service may also be a factor since m
Hi and thanks to all that has answered my previous post. I will consider the different options at hand: Purchasing material locally and braking my self Having a local shop make it Import a chassis ki
I have digged thru my junkbox and found an old tank switch that I bought at a swap meet. The switch have ceramic deck "holders" and looks like it is quite rugged. You can see some photos here: http:/

I am working on some loss estimates for the tank circuit of my GS35B amp. design and I am considering if silver plating of the tank circuit coil is feasible or not. I intend to use copper tubing inte
Thanks to all that have answered my post about skin depth and silver plating of tank coils. My conclusion is now that tank coil silver plating is not necessary for this appliaction. My tank coil will
I am looking for a hipot tester / high voltage breakdown tester. The voltage range should be approx 0-15kV. Should have voltage and current readout. Will use iton 230V AC, however a tester made for 1
Hi. I have posted some pictures of my new HI-POT tester at this link: http://www.lb3hc.net/hipot . Take a look if you are interested. Spec: Output range: 0-12KV DC. Output 1: metered 0-100uA@12KV Out
