Great Amp!  Time owned: more than 12 months
This is an excellent little amplifier that dates back to the 50s that uses a single 813 in the final. By using separate broadband couplers in the grid and plate circuits, it does not require any tuning. The 600L is designed to work 160, 80, 40, 20, 15 and 10 meters.

Designed to work with the SSB transmitters of that day, the 600L only requires 8 watts of drive (2 watts AM) to obtain full output. With this in mind, care must be taken not to overdrive the 600L with today’s 100 watt transceivers. I use an attenuator on the input to keep this from happening.

Another unique thing about the 600L is that it uses an 812A tube to regulate the screen supply. This gives the screen supply better than 1 % regulation for any load or line voltage change. The plate supply uses a rather hefty plate transformer and swinging choke in addition to a large 45 mfd capacitor, to give 1800 volts for the plate supply.

I give the 600L high marks for its design and operation. Just a pure joy to operate.
