This kit for the Dynaco PAS3 allows you to take out the power indicator bulb and replace it with a much more efficient LED. This takes some strain off the transformer and the unit will run cooler. 

Sorry but I had to remove the install bolt from the kit as it was too thick to send in regular mail. These kits are sent in an envelope with a stamp so there is no customs, duty or tariff. To install the board in the PAS3 or PAS2 you only need a 1" 6-32 bolt and 3 nuts.
