Power Transformer wanted for Scott LK150

GlassAudio · 29th December 2004, 06:55 PM

I need a Power transformer for my HH Scott LK-150 amp. The part number is TR-30-4-2, the specs are not all known so I have included the LK-150 schematic. I am not a EE and do not know how to calculate the transformer specs from the schematic. Perhaps someone here would be kind enough to do that for me. Thanks to all....

I have looked at the schematic and have a part that can be used as a replacement but you'll require a terminal block or wire connectors to splice in the additional leads. The part number on it is 5584-701227. It is a copper shielded frame type transformer weighing about 7lbs and much more durable than the part that failed in your LK-150. This one won't even get warm with two amps because it is designed for 8A. I want $30 for it. Calculate shipping from 11201 and add it up.

Thanks for taking the time to look the schematic over. You said I would have to splice in or add a terminal block for additional circuits that are needed. What circuits are affected? What brand of Transformer is it? I tried to find the part number and had no luck.

Email me for more information. It's a working pull from a vintage Harman Kardon.
