That transformers construction looks familiar. Several of us used a transformer manufacturer just outside of LA which was called Woodys transformer at the time. They wound about all the transformers

Hee hee. Thanks Bob, nice to start the day with a nice laugh. 73 Jim SM2EKM -------------- Robert B. Bonner wrote:

Yeah who needs fuses? Current limit with the power company. Hello? Yes this is NUKE STATION #6, yes this is SM2EKM I'm coming on line, pull the rods out.

I have two linear power amplifier units for sale: 4XSD1427(THX15-C) in parallel push-pull in each unit, with driver stage and large heat sink.RF output power( each unit):400W, freqence

Peter, It might be a good idea to contact SM2CEW http://www.sm2cew.com/ampli.html If it costs already a lot of time and money I would invest 100 more Euros (for new Parts) in a well regulated screen

Good afternoon List ! I'm new to the list. Today I got a tip G2DAF experts might be around here. From various sides I got incompatible advices on the G2DAF concept for a HF linear ( SSB speech ) PA

Hi all, There is a collins amp on ebay that uses a pair of 4-400s. I wonder if any of you guys know anything about it. I have a couple filter blocks from it. This is the box on the right rear of the

Bob, I think I ditched the idea with a fuse. What the heck, if my 8171 box doesnt have a fuse why bother with this toybox. 73 SM2EKM ------------- Robert B. Bonner wrote:

I see. Well its getting strange. As I wrote before, in the manual I have someone had written 15 ohms on the schematic, there is no parts list in the manual. However I have two L-4Bs here and I see now

The L4B manual out of my file shows 3 - 15 OHM 2 Watt resistors as the Parasitic Supressor BOB DD

fired watts was Nigel, I also have a FL2100z, just got it going again after a mishap in shipping some years back(wonderful posties, AMP a tad heavy I guess) Anyway what sort of input Ia was the beast

Jim == The suppressor resistors are paralleled with c. 80nH of L. What frequency would be required to develop enough V-drop across 80nH to fry the resistors?

A timely question: Why did the resistors fry?

I must put this right. 15 ohms was wrong, sorry! Explanation: Since I have no manual I have found one on internet, on the schematic someone has scribbled with a pen 3 x 15 ohms for the resistors,
