and selector switch for 3 inputs.

this one my GF calls the " zhou bidze " Pigs Nose....

i must admit, there is some resemblance haha
I like the input selector switch to make it a complete integrated amplifier.

any chance of ordering 4 sets from you? (I sent you a private email but without the input selector switch), but now I am very interested with 3 way input selector.

Default backside

im getting a new backside, the connectors are not positioned nicely. the speaker connectors are too close to the side.

also the VU meters will be 1mm deeper and get a shiny edge around them

Hello Arjen!

Which tripath chip is inside this amp on last two posts and how much will be the price range if you decide to sell them?

Default Amps

Hi there,

This amp can be equipped with TA2020 or TA2024, witch ever you prefer

the price indication is around 120 Euro, i hope i can get that price down, but it depends on quantity and my negotiation skill in Chinese ;-)

for that you get a fully finished amp with 3 channels input valve pre-amp, MKIII board and 3.5A SMPS powersupply inside.

i hope it will be done around 2 weeks from now.

Greetings!

Hi Arjen,
what kind of preamp you use? CF? Tube? PS voltage?

I like to use your old green boards (modified) with different tubes headphones amps, gain is too much, but I like how it sound.

Zigis.

Hello Arjen, I've bought your MKII TA2020 and it's the best amp i've got now, really nice sound!! The reference was a Gradiente 4.1 mini system with LM3886, and a Yamaha receiver, but your amp is much better, more open and the the highs, mid and low are much more detailed. Of course, i'm not talking about power, but I hardly need to pass 40-50% my volume.

Can you describe the difference of the sound using or not the valve preamp??
I'll be watching your ebay for new things =D

Thanks in advance!

Whelibob,

Yes, i do not sell kits, just fully finished boards.

Zigis, i use a double triode 12AU7 valve for this, the amp was designed for me by a friend that used to design for Siemens ( 20 KW FM transmitters, enz )

Its more a Valve Buffer, it does not amplify, it changes the sound so that it has that tube warmth and smoothness, making the TA amps sound like a valve amp.

the plate voltage is made with a cascade and a NE555 IC, very simple, no noise and a band with or 253 KHZ at -3DB, so, plenty!
the NE555 works at around 40-50 KHZ switching frequency.

the plate voltage is around 40 volts, more than enough since i don't want gain!

the tube board only needs 12 volts, the NE555 works off of that.

Greetings!
