Duelund 12AWG Biwire Amp runs hot

Hello all,

i have bought the Dueland 12AWG Cable to build a Biwire Speakercable by myself.At the amp end i crimp the cable with WBT Spades bevor i crimp the cables with insulated conductor sleeves. At the speakerside i crimp the cables (four for each speaker) with insulated conductor sleeves.The Sound is very good, but my amp is running much more hot than bevore.Bevore i use Harmaonic Tech Pro 9 plus speaker cable.Why does the amp runs so very hot with the Duelundcable?My amp ist an all Tube Design with 2x50 W.I change only the speakercable - nothing else.I am sorry abou my english.Thank you for reply.Kind regards Dirk

If the only change you have made is installing DIY speaker cables then the problem logically should be with them.

12 AWG should be ok so maybe you have a short circuit. You need to FULLY remove your cables from your system and do an insulation test.

Are the cables true bi-wire? 4 connections at both ends or shotgun 2x4?

To be double sure put the old cables back in to see if the amp still gets hot.

Have you checked the amp's bias settings?

Lay one cable out on your table, using a multi- meter or continuity tester, attach a crocodile clip to the red amp side wire and then touch each of the speaker end wires.

You should only get a closed circuit on the red wires the blacks should be open circuit.

Repeat with the black amp side wire, the blacks should be closed and the reds open circuit.

Then check the other speaker cable exactly the same.
