Default DRV134 replacment , better chip ,THAT1646 SE to Balanced


These chip exact the replacement of the DRV134 or 135 with much better result . It is leg compatible .These for single ended to Balanced driver preamplifier chip. You can find the schematic for the full preamplifier on the forum , the PC board layout and the part list .It need only a few components .These is a break through to convert the SE amplifier to balanced mode .

Today many CD player has balanced output ,but we not really enjoy the advantage with out converting the SE amplifier to a Balanced mode .

The better chip than the DRV134 or 135 is THAT1646 .

You can see the test result here

Not to talk about hard to find the DRV134 or 135 parts . I see on the Ebay for horrible price .

You need two chip for stereo amplifier drive .

Any question welcome .

I have some quantity but I want to keep some since hard to find them .

I use these in excellent result , the amplifier connected in bridged mode , much bass, better dynamic like total different amplifier would be.The price is for one piece but you can buy up to 18PC if you want . I take paypal if you pay for the paypal fee .

I will ship world wide , the buyer pays for the shipping and insurance .

Thanks for the interest .

Do you have any of these left? I'd like to get a few.
I'm in Toronto as well, could I pick them up?

I left exactly 8PC for sale .
I only can take for payment postal money order , Western union money transfer , or certified cheque .
Unfortunately I'm no longer registered with Pay pal or Ebay .
I had over 350 positive feedback .
I ask $6/PC and $8 for shipping .
I will ship as a gift so you do not need to pay any custom etc .

It might be a good idea to have a Paypal account. The other alternatives, in Europe at least, are stone age.
