Arjen Helder TK2050 Mono Amp

[shrayv]

I am looking to do a DIY build of the TK2050 mono amp sold by arjen on eBay. Just wanted inputs on what power supply should be procured for this build?

Read a few posts on diyaudio and noticed a few users using a single 24v 5A smps to run both the boards.

I have a few questions
1) does it make sense power the boards using a smps for each board?
2) could a toroid transformer be used to power both the boards?

I'm a newbie to DIY and have no knowledge in electronics, soldering etc...

Looking for your valuable inputs

Just saw this.

You can use both kind of power supply with 24V-0 single rail. SMPS as well as linear both will do and have more or less same results.

For SMPS, 24V 5A/channel will do. You need to buy two and power each mono separately.
For linear you need little bulky PS. 18V, 300VA for both channels.

I feel go ahead with good quality SMPS! I could not locate one above 12V.

We used Axiom Energy Power supplies at a past job and they are pretty good.

arjen helder is well regarded in diy community for his T-amps. u can purchase his boards with trust. in an email communication i put a similar question about SMPS suitability. as per his reply and some forum discussions, T-amps audio performance is not very much affected (means ill effects of SMPS are negligible) by switching power supply. please keep us updated about your experience with this amp
