Eric, Have you considered an antenna tuner or modifying your antenna to address the problematic load? David KD4E -- *David* KD4E ARES-EC Bulloch County, Nevils, Georgia USA Safe & Secure Search Engin
I like the Dentron MLA-2500 and am seeing lots of them for sale at Hamfests and online. I understand that the "B" model had a tap for higher voltage for higher SSB power, but otherwise was the same a
included a tuned input - none that I've seen for sale have included that option. Has anyone seen sales ads/flyers from Dentron promoting a tuned input as standard in the "B" model? David KD4E -- *Da
Is $250. - $300. each still a typical price for good used? Or has Ham-flation (obsession with amps + tube hoarding) driven the used cost up considerably? David KD4E -- *David* KD4E ARES-EC Bulloch Co

Other than price, $100. for Harbach and $125. for TheHeathkitShop are there any important differences between these two power supply upgrade boards for the Clipperton L? http://harbachelectronics.com
Would these caps be safe to use in an amp PS? Samsung 120 mfd at 450 volt 105c Would this # EIAJD0160 reveal the date code? Or best not to mess with anything below 500v? The Clipperton L manual says
OK, sounds good. I'm still trying to sort the alphanumeric label EIAJD0160: EIA = military contract? J = ?? D = ?? 01 = 2001? 60 = ?? If 2001 they are already 14 years old - perhaps not a good choice
Kathy, The bottom section of this page may provide some ideas: http://www.w8ji.com/loading_amplifier.htm Since you've looked at some other possibilities in the air variables I'm going to guess a padd
Bill, According to the SPE home site: -- Continuous use MAX mode: SSB / CW unlimited. Automatically switches to MID for a while if, in MAX, a continuous signal (RTTY) is transmitted. MID LOW modes, R
PEP is not the same thing as key-down RTTY by a long shot. How many switches, feedlines, and antennas, external to the amp can survive 1500w carrier for long? Especially heating at imperfect and/or m

There's the point - how many Hams have taken the time and invested the money to make sure that the entire chain is up to the task? As more and more cheap Chinese junk floods the market and the econom
Was it a Cadillac hearse? "Timtron" WA1HLR? I remember a guy with a Collins S-line including a 30S1 in his Cadillac, but nothing more. 72, Roger (K8RI) -- *David* KD4E ARES-EC Bulloch County, Nevils,
An inexpensive single device simple amp (no autotuner, no bells & whistles) could run clean & cool at 600w? http://www.eham.net/articles/34850 10 dB above 100w at received end? $200. for the device +
I respectfully disagree - unless one demands only a full-legal amp. SB-200's (and many similar power-level amps) sold like crazy in the past & are still being resold daily. A 600w SS amp is not expen
For those who must have max-legal the 600w proposal is meaningless. For the 10's of thousands who have owned and happily operated 600w amps for decades it is not. It is to that population I direct my
What might it cost of someone made and sold a filter like this? For a homebrew driver source, variously rated 10w, 120w, and for an amp 600w and 1200/1500w? http://www.qsl.net/wm5z/qex199907.pdf 73,
