For many people, the existing EEDTS booster, which has an output current capacity of 10 A, is perhaps a bit too much of a good thing. Although the existing booster is significantly superior to the ‘Budget Booster’ described here in many respects, the latter booster is more suitable for making the transition from analogue to digital control for your model railway. You can even use your old reliable train transformer (AC) from the analogue era to power the new booster!Note: although the Budget Booster can also be used with other controllers, since a symmetric signal can be connected to K1 and K2, this circuit is intended to be connected to the EEDTS Pro controller. The connectors are labelled to match the connectors on the EEDTS Pro controller board.
