- From the transformer primary wiring, yours (240 V) is different from mine (230 V), although I understand there is no "significant" difference, wonder if I can find the "correct" connection for my 220V mains. Guess time to do inductance and DCR measurements on the primary windings.
I don't think it will make a blind bit of difference. Anywhere between 220 and 240 should be fine.
- Since you're using the Hakko 816 handle, did it come as standard ? Or you purchased it separately ? If you did, what happened to the Hakko 809 handle ? Troublesome ?
It was an option at the time of ordering.
I prefer the pencil style over the gun style.
- About the pump diaphragm, looks like the membrane probably got pulled while secured or someone did it wrong ? (pointed by red arrows) I guess on next cleaning, you need to replace it as it may leak at that spot, cmiiw.
My photo is a bit misleading.
The lower corner had peeled up a little when I removed the pump head.
Smoothing it down (after I took the photo) resulted in a perfect seal once reassembled.
Looking at yours, I am not so sure about the NOS status.
It looks well used with the apparent flux damage to the diaphragm.
I may be wrong.
