1. [Amps] 234v - to convert or not? (score: 1): Author: Ken Bessler <kg0wx@hotmail.com>; Date: Sun, 14 Sep 2008 19:09:45 -0500; I just picked up a NOS Yaesu FL-2100B. I used to own a TL-922A and for that I installed a dedicated 234v line in the shack. My 117v lines are a little crowded so I was thinking about converting the F; /archives//html/Amps/2008-09/msg00130.html (7,817 bytes)

If so, check the IR drop between the breaker and the outlet. I recently restored a FL-2100B for a local disabled ham. His ri; /archives//html/Amps/2008-09/msg00131.html (9,527 bytes)

Since 240V is a simple process, go for it. Drop should be around 350V then. Id also check the filter c; /archives//html/Amps/2008-09/msg00133.html (8,867 bytes)

Usually there are 8-16 of them in series, with resistors across them to equalize the voltage across them. It's not uncommon for; /archives//html/Amps/2008-09/msg00136.html (8,634 bytes)

(score: 1): Author: Bryan Swadener WA7PRC <bswadener@yahoo.com>; Date: Sun, 14 Sep 2008 21:47:02 -0700 (PDT); Hi Ken, A 'stiff' HV is a very good thing for dynamic loads such as SSB. It starts with the AC mains. Back in the 70s, I bought a new-to-me Heath SB220 that was wired for 120V operation. It didn't ta; /archives//html/Amps/2008-09/msg00137.html (8,930 bytes)

So why not measure the input mains voltage at or near the same socket and see how if performs when keying the amp? In my last house, I found I'd lose about 10V from 240V when the amp was; /archives//html/Amps/2008-09/msg00139.html (9,083 bytes)

So, you can determine the capacity of the electrolytic capacitors without even taking the amp apart. If you are l; /archives//html/Amps/2008-09/msg00141.html (8,246 bytes)

Here in the US, it's common for homes to have that much load in the form of a couple; /archives//html/Amps/2008-09/msg00143.html (8,527 bytes)
