[TR] TR3 Maradyne Heater

[William Brewer]

No Problems Jonmac,
     A Maradyne heater is an aftermarket heater made for a farm tractor cab. 
It'll sort of fit in a TR3 and when I installed it it really pumped out the 
heat. Now it won't.

Hi, Bill
 
At the risk of being a PITA, what is a maradyne heater and how does it differ 
from the original unit?
 
Cheers, Jonmac
