Re: [TenTec] Pegasus 550

["Denton" <denton@oregontrail.net>]

I used to have a Peggy, and one of the relays on the band pass filter board 
failed...if I remember right, the relay coils for both input and output of 
the filter are wired in series...I replaced mine with two new relays that 
had 6 volt coils.
