[Heathkit] meter basic movement in SB 220

[John King via Heathkit]

In the back of my feeble mind, I seem to remember that the movement in the HM102 watt meter is the same as the plate
current meter in the SB 220 and the HM 102 meter can b used in the SB 220 with a swap of meter faces from the the HW 102 to the meter in  the SB 220 or Vice vesa. Please tell me what you know about the interchangeability of the Hm 102 movement with the plate current meter in the SB 220. Your input will be greatly appreciated. 73, John, K5PGW
