That Viking I was a great experience for me. I learned a lot from it too. For the 813, it was an 813 adapted into an 814 base after my 814 died. I used a FW bridge on the Viking I HV supply to get ~ 1500 volts. I used an outboard power supply for the 8417's producing about 550 volts and 300v (regulated). I could get about 150 watts output pretty easy with that rig and still have good AM performance. I had a 125w Stancor polypedance mod transformer. This was a 160-40 rig only.
BTW, that was back in 1975 time frame. Those same 8417's are still in use at ARS W5OMR..

Outboard power supply and/or modulator? What were you running for plate voltage on the 813? -Larry/NE1S ______________________________________________________________ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body. ______________________________________________________________ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
