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 ; D.paste , at least one surgical tweezers ; needle nose pliers & Cheap Analog Multi-meter. 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 - +.Relays.

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.

Ah back in the day. This was the3rd Amp I owned. 1 6LQ6driving 3 6LQ6. Decent 240-250 RMS. Output.

Sold it years ago after re-tubing it to 31LQ6.

Lots were made. It was cheaper than the Palomar Skipper 300 or Palomar 90A. Palomar 300A,300Z. & D&A Amps.

This Amp also showed up under other names and slightly different configurations. 20 Meter/40 meter etc. You simply swapped out the original Coil to a 5 turn if I remember correctly. You could Tap/jump the Tank circuit coils trial & error also for \"10 Meter operation\" of course.

Read the Skipper 300 Add to find out why and a bit of directions. Schematic is online.

Nice looking Amp to gowith ones Tram Titan etc.

High Voltage KILLS. So unplug. Discharge old HV Caps. A Shorted capacitor on this Sweep

tube Amp in my experience usually took out at least 1 rectifier diode before the fuse saved the day.

A novice can rebuild this Amp.

3 x 450 v Radial HV radial electrolytic Capacitors

8 x 3 amp 1000piv diodes

1x 220uf radial 50v

1 X 47uf 25v

3x 2905 transistors 1 extra just in case!

Not much difference between240and 300 watts RMS !

Worth restoring if you have one complete with a good 2x HV transformer.
