hi,

i bought a pair of ALTEC 15095A transformers to use as a SUT for my denon 103r. Unfortunately i am just a fool with a soldering iron and i cannot read/understand joseph esmillas wiring diagram. Could somebody with more knowledge than me please draw me a foolproof wiring sketch on how to connect the two transformers to rca in/outs and a ground lug?

i would be immensely grateful, thank you all in advance,

oliver

Hi Oliver, welcome to the forum. Can you post a datasheet / schematic?
Cheers, Gio

Cool, looks like they can be plugged into octal tube sockets.

The datasheet tells you how to connect for either 150 or 600 ohm load.

The attached schematic is for 150 ohm.

Connect your input RCA to pin 1 (signal) and pin 3 (signal ground).
Connect your output RCA to pin 7 (signal) and pin 8 (signal ground)
Pin 4 is connected to pin 1
Pin 6 is connected to pin 3.
Pin 2 is connected to both pin 6 and 8 (model 159095A only) and this is the ground.

BTW - here are Mark's Lundahl MM Phono Step-Up Transformers

You are welcome. If you get unwanted hum and noise, try connecting pins 2 and 3 (ground).

hi gio,

the guy who drew me the diagram stated:

Run wire from the ground connector to pins 2,6 and 8.

are both ground wirings possible?

thank you, oliver

You can connect pin 2 to anyone of 3, 6 and 8 since they are connected.
