couple of months ago i put some “System Photos” up in the appropriate topic and my DIY line selector (for choosing between different DAC/EQ/Amp/Spkr combos) was favourably commented on, in particular the cardboard box “prototype case” it was in at the time (and the pill-bottle remote also)
They are now in aluminium cases (thanks eBay).
Also now working on unit 3 & 4
These are both effectively “pre-amps” so somewhat more conventional - one will be for analogue input routing to feed into the ADC of the digital chain, with no remote and a switched attenuator to set level going into ADC.
The other will be used as a preamp on a separate system, with remote motorised volume and remote switching of the tape loops.
“Tape loops”?! Yes - in case I get reel-reel again, but also always useful for external processing if I wish to clean up a record that is going into the ADC via the preamp.
I thought long and hard and realised that switching inputs on an analogue preamp is marginally useful only, but switching the insert loops in and out is rather more useful, whether comparing processed / dry, or comparing in and out of a 3 head tape machine.
The pill bottle remote has been “updated” too
I seem to be creating a product line…
So from cardboard:
