"Hi wanted to say I really appreciated you making these power supplies.
I also appreciate how you state everything not hiding anything,
I was told many years ago by the Australian distributor that they were no longer supplying parts for this series mixer as was discontinued, the previous designs seemed better and had external power supply.
In some little confrontation when it became evident that there was a manufacturing design fault which they admitted to, but essentially nothing was going to be done other than offering parts at “cost” which was more than your unit from memory anyway.
At that point in time I purchased several of the power supplies about 8 years ago that has kept us going up to about a month back. In total we have three of the mixers but have burned through around 7 psu’s in that time.
As the mixers run 24 hours a day when in use, the psu’s do like to fail for the heatsink, surge, etc. I notice the replacement soundcraft psu had a better heatsink so is less prone to fail but they still do.
The ES series mixer is the only mixer available suitable for radio less than $1500USD with more than 6 stereo inputs that I/ could ever find. Every mixer under $1000 has maximum 4 stereo, apart from one 8 channel broadcast mixer which I could find, which is not enough channels for us.
At some point we need to go to an broadcast mixer but this has kept us going to date.
On our mixer I had to move the ground to the right as there wasn’t the length of ground lead to leave to where the factory ground mount is.
I also had to drill out the hole in the ground larger so that it would fit the factory ground bolt.
The only other point I would make is I was unable to put both washers on and just used one washer and 1 spring washer, for the teroidal fixing kit, I am sure I could have but after about ten minutes and multiple attempts I gave up.
I am a novice at understanding ohms, so I only know continuity. but understanding what is considered high or low on the 20k setting was a bit of a question. It is good that you show the ohm meter, and what settings were showing on it, however mine was reading differently on the tests, so for me was a question." - Mike
