2x100W at 4 Ohm TK2050 Class-T Audio Amplifier Board Only
2x100W at 4 Ohm TK2050 Class-T Audio Amplifier Board Only is rated 4.6 out of 5 by 15.
Rated 5 out of 5 by from Works great with transformer power supplyI installed this in a boom box to replace the original logic board and amp. I used a standard 12v transformer with a bridge rectifier and about 8000uf worth of electrolytic capacitors as a filter.I expected to hear a mains hum because switching power supplies are recommended for powering the amplifier. The unit is dead silent when not in use.

Rated 4 out of 5 by from surprisingly good sound quality and power!I bought this amp about a week ago and I couldn't be happier that I did. I used the amp to create a small desktop integrated amp that wasn't ridiculously expensive and still had good power output and could deliver a quality signal.If I can find an image I will attached it at a later point, but what I basically did was enclose a power supply and the amp in a nicely painted wooden box for my desk. I put a 50k logarithmic pot in for volume control, and a three way 2 pole selector switch for selecting between three inputs.However this amp isn't without it's faults! the installed power supply capacitors are WAY too small. On the board there is a bank of 8 220uF 50v caps all in parallel. this produces a net capacitance of 1,760uF at 50v. To put this into perspective, I'll use the Dayton DTA 100a as an example. The DTA has one TK2050 chip in it and used a 2,200uF 50v power supply capacitor. In that application that capacitor is too small, to get the absolute BEST performance from the DTA's integrated TK2050 chip it's recommended to used a 10,000uF 50v capacitor, almost 5 times as large as what's installed.So for Sure Electronics to think it is alright to put TWO TK2050 chips on a board and give them half the power supply capacitance that Dayton gives to ONE TK2050 is absurd. If you buy this board PLEASE upgrade the capacitors! It's an extremely simple mod that yields immediate noticeable results. All one has to do is remove all the capacitors along the sides of the board and wire one 20,000uF 50v capacitor into the holes of one of the capacitors that was removed. Having this extra bank of power available to the amp allows for deeper and fuller bass response and help make up for shoddy power supplies. I've included the part number to a capacitor available from DigiKey that is a good quality component with the appropriate specs. ECE-S1HG103Z simply buy two of these and wire them together in parallel, then connect the bank to where one of the original power supply capacitors were. It makes an enormous difference.Further I noticed that one of the adjustable voltage regulator on one side my board gets very hot, much hotter than the one on the other side. It's temperature is within the listed acceptable operating temperature from the datasheet so I can't really fault the board for this but it does seem wrong. I believe it's u4 on the silkscreen, and it's the small three legged component near the channel 2 input. If somebody else has a similar problem I'd love to know so we could possibly get this fixed! (note! My board is modified but this component was operating hot from day one when I first got the board.)Also the DC offset on this board is worth checking before it's used on any speakers. Since it's easy to adjust I recommend everybody who buys this board double check what their DC offset is as some people reported it being way out of spec. Just set your Multimeter to the 200mv DC range and measure the voltage across the speaker terminals when the amp has no signal. My channels were at 30mv and 50mv when i got the amp and I was able to dial them both down to about 15mv with some careful tuning. There's two adjustments for DC offset located under the heatsink, I wish Sure would have put holes in the heatsink to make it easier to adjust these parameters but that's a minor issue. Try to get the DC offset as close to zero as possible without going negative.Overall I think this is a great product and I'm glad PE stocks it, I'm a huge fan of T amps and I love their sound and effeciency. I would recommend someone buy this amp OVER the Dayton DTA120 that's currently available. With one simple mod an two simple adjustments this amp for about half the cost of that one absolutely blows it clean out of the water.Great product, I'm glad I own one!

Rated 5 out of 5 by from Sounds great!When it comes to precise stereo image and speaker control, both in the midrange and bass, this is the best amp I have ever heard. This results in a extremely detailed and "tidy" sound. Very studio-monitor-like. I use it with a Delta 24V/150W switch mode power supply. It can be adjusted up to 27V. At this voltage the max power before clipping is about 2x30W/8ohm anf 2x55W/4ohm. This amp needs a long run in time before it sounds good, in my opinion about 15 hours.

Rated 5 out of 5 by from A great amp !! Work excellent !I bought this unit about 2 weeks ago. I'm very pleased with its performance.I would definitely recommend this product without any hesitation. Thanks for offering such a great product !

Rated 5 out of 5 by from Good replacement for older ampsI got tired of repairing the two driver boards in my Sansui 5000X. I bought the Sansui receiver/amp in 1971 so it holds sentimental value for me. This little amp fit very nicely in the 5000x chassis after removing the driver boards and capacitor banks. I had a 12volt, 4 amp SMPS that fit the underside of the Sansui chassis.At this price point, this little amp can't be beat. Although mine only delivers aprox. 48 watts it drives a pair of ESS AMT PS-820 speakers with ease. Those with less efficient speakers would want a larger voltage/current PS.Products quality is outstanding and parts placement is well thought-out.No knocks for this product so far.

Rated 5 out of 5 by from Very Good soundI have 2 tuba amps which costs several 100 euro each.But this amp seems to beat them.....Never expected this quality.

2x100W at 4 Ohm TK2050 Class-T Audio Amplifier Board Only

The product title refers to this component as a class "T" amplifier, yet in the features and specifications, it is described as class "D".  Can anyone explain the discrepancy and provide clarification on the actual classification of this component?

Asked by: neurotopia

Hello, I dont have to much experienxe with this but can I use this board for a subwoofer and how? I only have a 8ohms speaker. Other Question: Which board I can use for a Bass Amp and how? Thanks

Asked by: carollyjafy
This is a full range amp board so you would need a low pass filter to use for lower frequencies.

Would this amp be too much for a 35w rms per speaker.  If I understand this correctly, the higher the input voltage, the higher the output.  If I had my power supply at say 13v, could my speakers withstand this amp?

Asked by: gtanna
Having 'too much' power is never a bad thing, as long as you understand the limits of the speakers. If they are distorting noticeably, they need to be turned down. This amp will work fine with 35 watt speakers.

How many watts will this amp be pushing with two 3-way speakers ( 1 per channel ) speakers are rated 140W max.

Asked by: joemonata
The power an amp delivers is actually determined my the impedance of the speaker, not the type.it is capable of 100 watts per channel when driving a 4 ohm load.
