I'm off work for at least another year. Allows me to look after the child while she does an MA in social work and gets a social work job .

So my next project is speakers. I'm keeping the boxes , they are infinite baffle with a sperate enclosure for the 5 inch midrange and a whole for a 12inch driver. I can't go back to a smaller woofer and there aren't a whole lots of 12inch woofer boxes. The only real problem is they were made in 1974 and aren't mirror image
..
.I'm getting the paper scan speak midrange , currently looking at 12 inch and tweeter .

While I contemplate what to do next to my hifi ( it used to be what can I hard wire or what material can I use to put the turntable on , it's funny how your perspective changes when you actually make your hifi)

I thought Id change the stepped attenuator . I bought my p50sa of a member for £200. I have no reason to believe it was in anyway altered. The s.a was noisy and it was showing signs of channel in balance on certain steps.
.
So I bought one from that there China. £45 and 16 days later it arrived.

So me and my one arm/hand looked at it , 35% smaller ! and left it in a cupboard.

Well today some 3 months later me and my one arm/hand fitted it. It was easy as pie , despite the size differential. Plugged it in and blew the whole house electrics. Emmm. Plugged it in again and blew them again. Shit I thought better put the old one back .

Got the passive on my work bench/dining room table. Bollocks I had shorted it , it was obvious wires were touching. So I resoldered it all with an attention to detail that one hand frowns upon.
.
Pluged it back in and what a result . Not only does it work. It's silent and theres a level of detail that wasn't there with the old one.

Richard , yet another conversation I would have had with you . Death it's shit and deosnt stop being so until you die . Then it's somebody else's concern if your deserving.

Glad you got it going eventually.

Attenuators can really make a difference - switch quality, type of resistors.

Nothing beats no switch at all, just two resistors per channel soldered together. Can't change the volume though without doing a bit of soldering :lol:

If you only have one source then you might as well bypass the selector switch if there isn't already a direct input. Further improvements :dance:
