Up until today I've been working on the power supply board and the VU meter buffer.
This morning was the designated time to steel myself and solder the surface mount OPA1612AID, OPA1632D and OPA1611AID op amps to the Alpha 24 circuit boards. Probably the most tricky soldering job I've ever taken on, I really wasn't looking forward to this.
Aside from a couple of instances of the chip sliding out of kilter when trying to tack down the first leg, I think it went reasonably well. The solder has flowed around the joints okay from what I can see under a magnifier, and the joints proved solid when tested with a multimeter. I tried to keep the contact time to about a second for each of the legs, so hopefully I've not cooked anything.
Anyway, here's a pic of the A24 circuit boards as they are right now (right) and their regulated power supply board (left) - as you can see there are still bits left to be populated. The penny is for scale. Resistors are all Vishays - CPF for 2 watt, CMF series on the A24 boards and RN series on the power supply.
