What B+ are people using on the 813 ? I think the original

an 813, but possibly the modulation transformer will not 
stand a higher power level ?  -Hue Miller 
Originally 1150V. (750 at high altitudes) but hams regularly run these sets at 1500-1600 volts (and higher) and get away with it.  One limitation is the zero biased 811s in the modulator and the audio drive available from the speech amp.  The mod xformer in the ART-13 will handle remarkable power levels considering it's small size.
