Aoyue 701 Desoldering Station.

[henas]

I have Aoyue 701 combination vacuum desoldering/solder station not an "A" version. I believe this is knock of the original Hakko 701.
Playing with heating elements I managed to short solder part of the circuit. Desolder gun still works fine. Unfortunately two Ics 14 pin and 6 pin have their marking physically removed. 6 pin IC appear to be driver for the triac and seem to be OK but the 14 pin is cooked. I suspect this is quad Op-Amp maybe TL074.

Someone might know what IC's were used on this Chinese knock off. I suspect the same as on the original Hakko 701.
I already ordered heating element controller from Ebay never less would be nice repair it too.
