new Battery powered TK2050 Amps! 2 right now, I might build more later.

Hey guys, I have put together a complete amplifier kit using the TK2050 chipset and cigar box enclosures. This is for all the people who might not be ready or have the time to put a complete amplifier together. They sound amazing! They totally beat the pants off of my "boutique parts" Gainclone in terms of sound quality (not raw output, of course). In my opinion, the TK2050 is the best-sounding T-amp.

the eBay listing has all of the info, check it out. These are new, I've been building them in my spare time on weekends.

The price is $395+$20 shipping. That includes an Amp, Battery Box, Charger and input cable.

This is not meant to be a criticism rather an observation, your main board looks that that board from China which cost $50, then you add, input caps, 2*RCA, 2*cigar boxes and 2*batteries(I think), then you charge $395.

+ a good volume control + knob + switch + wiring + XLR charger socket + an auto-charger + a few hours of labor + a little bit of profit margin. It's really not unreasonable.

also, there is only one other fully-assembled TK2050-based amp available -- the Red Wine Audio Signature 30.2, and it's $3000. It has a nice case, an auto-shut-off, PIO input caps, and a beefed up output filter.

I'm offering something excellent that no one else has at this price point.

Okay, consider this:

- TK2050 board
- 2 Good MKP input caps
- 2 12v 5ah SLA batteries
- 24-step 1% SMD attenuator
- Auto-charger
- 2 gold-plated RCA plugs
- XLR Connector
- 2 Wood Cigar boxes
- Volume knob
- Mini-switch
- Various wires

- 3 build hours @ $40/hr

- A little profit margin


Consider that, then tell me how much YOU would pay for one of these? Thanks!
 
Hi all

I don’t have any idea how to modify these amps yet, but I cant see anything wrong with what this member is doing and if you enjoy doing it and people are prepared to buy the amps ready build that’s great.

It would be interesting to do a direct comparison with the RWA 30.2 and if it is as good as or better than the RWA then it is good value for money.

I wish you all the best with the sales.

I am pretty new to this DIY audio myself, bar from a little bit of tinkering over the years and I have been all over this site lately getting as much information as possible.

I have had some experience with tripath 2024 and I own a tripath 2020 at the moment they have lots of good points but I have found them seriously lacking in the power. So I have just placed an order for a tk2050 and a 24Volt mains power supply and Im still in the process of trying to locate a good case, I quite fancy the naim replicas but I am keeping cost to a minimum this time, this could be something to think about in future. Not very adventures so far but this is my first attempt.

I am going to put together a very simple power amplifier to see what these extra power chips are capable of and I will be putting it head to head with my Nad c350 power amp section (which I personally think is an exceptional amp for the money and a solid state) once I have the parts and it is complete I will see how it compares.

If it has got potential the next step will be the mods.
 
Looks good to me!

I love the look of these. Of course, I have used cigar boxes for a couple of t-amps, so I am not impartial. Anyhow, if I can save my pfennigs, I'll consider getting one.

Hey, has anyone reviewed it? Maybe someone could organize a road tour for one of your amps if you are interested.

I would be.
 
let us know the link when it gets there. I finally got to put one together with a 24V regulating power supply from the same site.

However I have managed to fry mine already it was working fine however I was switching back and forth comparing it to my nad c350. I stopped the music but I was leaving both amps powered up (to keep them warm) however on connecting a phono lead to the tk2050. It shorted something and the onboard lights lit and smoke came from somewhere then the fan stopped and it never worked again.

I am pretty disheartened now as this was my first project. so i have a power supply but no amp.

on the first few listens I had of the amp I thought it was good it seemed to be very detailed but I thought the nad may be a bit more musical and a bit nicer to listen to, to be honest. first impressions were the vocals were not as nice on the tk2050. Weather the tk2050 would have improved with time is another thing, I would like to get another one eventually as I think this one may be fully U/S I don’t know, but Im on hold with the amp building for a bit.

was really surprised at the power of it though, ive had a few tripaths and this one is by far the most powerful, had a lot of grip, I needed a lot more time with it and I would have love to had a longer comparison with the Nad.🙁
 
Hey dude, just a piece of advise.

The charger you sold with it has too high charge current for the battery you deliver with it. Lead acid batteries produce hydrogen gas when they charge and you should therefore never charge at a higher rate than the battery manufacturer advises. this is highly unsafe and can cause fires and even explosions.

It's ok to sell home brewed electronic gear, though highly recommended to know about safety and regulations if you don't want to get a lawsuit up your behind.

Then I totally agree with EVA about the modifications to the unit. I suspect you don't have a spectrum analizer ranging up to at least 1Ghz to back up the safety and effectiveness of your mod? It will certainly influence the performance, but it is certainly not to the benefit.

I am sorry to have to place this post because I like it when people home brew things, but I feel twice as sorry for the customers buying your unsafe products.
