Mystery OTL maybe??? (pic attached)

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

Customer sent me this pic of old used OTL amp he picked up. He says it looks like it is built in a computer type rack mount chassis....

Ralph (& fellow OTL fans), is this a Atma-Sphere unit???? Except for using a circuit board, it looks like a Atma-Sphere OT given the layout, use a 6AS7's...but I have not seen one before that looks like this.

Happy Listening,

He hand-taped the circuit board but had it made at a local shop. - Ralph 11:21:02 02/17/16 (3)

Yes, they are REL caps - ruffian 19:55:45 02/18/16 (0)

I'm pretty sure it was not built with the Teflons; they were added about 15 years ago. - Ralph 12:38:34 02/18/16 (0)
