AKA Wagner electronics.
They were located on Liverpool road Ashfield, near the 7-11 petrol station.
Moved to Parramatta road Summer hill.
Just up the hill from Bob Jane (Sloan street).
You need to be west bound from Sloan street and they are now half way up the hill to the Liverpool road intersection.
There are 2 enteries.
One just after the bathroom shop and one at the top of the hill JUST before Liverpool road.
Dunno if it is of much use, but as they are a place which sometimes has hard to get pieces, it may be worth sharing.
