ArjenShenzhen said> i have just finished a nice PDF explaining how to mod this board and get the best out of it, any one that wants this file, please drop me a mail and ill send it to you .

Hello there. New here, but very interested in the modded version of this board. I would want to power 5.1 speakers using analogue connects from my PC via this amplifier.

Is this a product that someone with minimal experience in this area could use for this? (got experience building computers however).

Anyway, just dropped you an email asking for the PDF as well as well as the easiest way to set this up to power 5.1 speakers from a PC using analogue connections and what other parts would be needed.

Thanks.

1. What's the best way to buy this product? PM/email you direct or go to your ebay shop? (Note that I can't PM you or email you from this forum as I am a new member, so you need to drop me your email)

2. Would like to have 6 full range channels. How much for the upgrade?

3. Does this accept the 3 traditional 5.1 analogue inputs (i.e. front left & right. Centre + subwoofer. Rear left & right.). I am simply connecting my PC sound card here via normal analogue cables.

4. Does this have traditional 6 channel analogue outputs?. (i.e. front left, right, centre. Rear left, right. Subwoofer.) I am simply connecting a traditional 5.1 speaker system here.

5. Can I just plug in European voltage or so I need an adaptor? Or am I better off with my own PSU and using 12volts - if so, is it easy to put in the PSU?

5. Any cases you know of or recommend that I can put this in?

Thanks.

Default TA2020 wiring

I have one of these 'new' TA2020 from Arjen.

I'm just getting round to wiring it up now and struggling to get my hear round the wiring from input - selector - pot - pcb.

I've worked out the alps pot pins, but my question is this:
The pcb only has one earth, so where does this connect to on the pot?
Does it connect to both earth pins?
Also the input selector has three output pins - presumably you connect both L and R input earths to one input pin on the selector? So the same question applies, do you connect this common input earth to one or both Pot earth pins?

Also - on the three pin pcb input, one is marked earth - which of the other two is Left and which Right?

I'm housing this in an aluminium case, with power transformer inboard. This will be high gloss powder blue enamel painted. On the front, three cream chicken-head knobs will provide: rotary on/off via a lorlin rotary switch; four-way input selection; and volume control. Very retro!

I'm very excited, but just got to get my head around this input wiring.....

I'm attaching this useful diagram of the Alps pot to help others

thanks anyone!

I notice you are in the UK - I bought a case like this from RS electronics which will house the plain stereo TA202 board plus Arjen's power adapter. There's a range of sizes available. I've been drilling the necessary holes with a hand drill and wood drill bits - it's alloy and so drills easily. I'm enamel painting it and then I'll put little rubber feet on

Banzai (where the image is linked to) do a good range of knobs too
