More progress…

So, here is this week’s completed projects! (I honestly don’t think I’ve ever been able to write that before, but as promised earlier I got some new rear panels so I was able to keep up the pace 🙂 )
I’ve manage to case and complete both the NE headphone amp and the ACP+ prototype boards and again – the time elapsed between completing the PCBs and actually being able to close the lid on the completed build has to be a new record for me 🙂
For the ACP+ I have obviously made both headphone and preamp outputs despite choosing a fairly small case (and it only just fits). Now, I don’t think the wiring on this one is going to win me any prizes (nor, I expect, is the slightly OTT chrome-plated volume knob…) but that doesn’t really matter now because it works well and it is undoubtedly a cracking amp – whether used as a headamp or a preamp.
For the NE-amp I only had the headphone output to worry about, but I still ended up upsizing the case a little bit because it simply looked and worked much better. Power supply is one of my filtered IRMs and that seems to work well. Again, I am a bit surprised that this old design can turn into such a well-behaved amplifier. Pretty stupid of me to wait so long to start building it 😉
Completing the “set” we have a Whammy-amp, namely the official board I bought and showed here. This build was supposed to be one of the easiest because of the all-in-one board, but actually turned out to be one of the most annoying I have done for a while. I managed to measure up the front panel incorrectly not just once, but twice (!). First I couldn’t fit the headphone jack and having fixed that I then found I could not close the case because of the tall heat sinks. It seems complacency is indeed a dangerous enemy… Either way, it’s now done and working 🙂
