Kenrich Eagle 515 500 400 Linear Amplifier refurb Kit HVCAP diodes & Transistors

Description: READ FIRST BEFORE CLICKING BUY IT NOW ! This is NOT AN OEM KIT. The parts in this kit will get your amplifier working because these electronic parts have the same function & electrical characteristics of the original equipment parts. All Capacitors are radial not Axial. Of course. Usable tubes. Functioning Relays. Some parts may be of a higher current or voltage rating than original. They will work fine. The transistors may not be the same part number. but they will work if installed correctly. E.B.C. Emitter Base Collector. You have to have TOOLS such as : 30 to 60 watt Iron or variable larger. soldering gun. Solder ; paste , at least one surgical tweezers ; needle nose pliers & Cheap Analog Multimeter. Optional but good to have. Transistor checker/Capacitor tester. A basic understanding of BJT transistors like emitter, base , collector LOCATION. The legs of the PNP or NPN transistors in the kit. How Diodes function. Signal & rectifier diodes. Anode - cathode. Capacitors - + relay's. You can teach yourself quickly these basics. DO NOT BUY THIS KIT IF YOU THINK IT IS "PLUG & PLAY" & DO NOT BUY IT IF YOU THINK IT IS SOMETHING Else OTHER than a Colection of PARTS to be Installed BY YOU. Due to several requests; Here is a kit to repair/refurbish the Eagle 400, 500; 515 series of RF Amplifiers. The schematic is easily found online. 3X Through hole Modern fresh HV Capacitors. 120UF 450 volts radial. 1X 100uf capacitor 1 X 1000uf capacitor 1 X 330uf capacitor.......original 300uf ? 4 x 2905 1 extra pre-Amp or Keyup transistors 8 x 1N5408 If a "open or Shorted Rectifier diode is found". It has been my experience it is on the "High Power Side of the R diode assembly. Replace them all with these 3 amp versions. VS original 1 amp. Please read the Palomar Skipper add to get an idea of how and why. Even if you are a novice. Soldering is easy. Just practice on junk electronics first. Do parts one at a time. On transistors mark EBC. Caps + & -. & remember. The Voltages are Lethal. Unplug Amp. Discharge High voltage Caps to ground. Best In a few weeks will offer a Re-Tube Kit. I still have a bunch of 26volt & 35Volt Filament Transformers floating around. Back in the day. Added filament transformers and re-tubed Eagles to 35LR6 & 26LX6. Apparently few have tested this Lame brained concept of running a bunch of sweep tube filaments in series off the line voltage. If you attach several voltmeters one to each tube. You will see a range from as low as 17v to a high of 38v on each tube. That is why the Eagles eat sweep tubes. Another Lame Brain idea. Just plug in 26LX6 ? Televisions that were designed with a "series " heater string only used 1 26LX6 (27LF6) in series with other odd ball filament voltage tubes. In this application. 26LX6 or 27LF6 filament functioned within 10% of the Tube Data rated voltage. In a grounded grid application. Your Eagle. These tubes in series together will not operate within 10% filament Voltage unless a complex circuit is added. I bet it was a Ham operator that designed the Eagle & produced them. Several of the re-tubed & upgraded with a proper filament transformer Eagles are still on the air. Using the tubes I put in 19 years ago ! I forgot to mention. Series connection.... 26 + 26+26+26+26+26+26 or 7 x 26 = 170v Nowhere in the USA do U have 170v AC line voltage. Nevertheless U have vacuum tube Geniuses advertising on Ebay Kenrich eagle 26LX6 " Its just a few volts difference". 7 x 20flx does not work either. 140v. Despite the obvious. Moronadon Techs full of flatulence will claim this excrement setup works. Remember that the Heater/Filament draws current....At a specified voltage !!! What happens when U up the voltage & current ? Another issue. No two Heaters even in the same batch run will be exactly alike. They fall within a range. Due to the fact that in a TV the odd ball filament Sweep was the biggest current Hog. Other than the picture tube. It stayed within 10% of tolerance : within a line voltage powered Heater string. Some of the smaller tubes in the string did not fare as well in the TV with fluctuating line voltage. But those tubes were relatively cheap. & so was the TV. Since the TV did not come with a Transformer. In the Palomar Skipper and perhaps other Similar amps using 8950. U can series connect 6.3 filament in pairs 12 pin compactrons such as 6LX6,6MH6,6LF6,6LB6,6KD6 even 6JS6 with reduced power. To replace 8950. However; due to differences in "Input" & "Output" impedance. RF Driver Tank Coil & Final Tank will have to be TWEAKED, to achieve "Resonance". With that Swap mentioned. If U connect Volt meters to each tube. None will be at the specified 6.3v or draw the same MA at the filament at idle or key up. However, they will operate well within the 10% tolerance allowed for sweep tubes. Yup U got it. U will have to tweak the Eagle once you convert it with a proper filament supply. Though all 12pin compactrons are similar. Only 6LX6,26LX6 & 8950 have identical input output impedance ratings. Just look it up on the internet. G is your friend. Oh U GOT TO ADD UP THE NEW TUBES specified current rating. Then find a transformer that will get you within 5% of the rated voltage for the tubes in parallel. Do not be a Moronadon . & waste yur money until U also convert yur Eagle & add a proper filament supply. 20LF6 does not work either 7x20 = 140v
