Information for Joule Electra LA100 Mark III

Glad to hear the latest version of the LA-150 does not use the Russian tubes in the gain stage. I unfortunately sold my LA-100 MkIII recently as a result of having to downsize my system a bit to move into smaller quarters and truly miss the preamps musicality in my system.

Jud - if you're following this thread can you elaborate on whether there is an upgrade path to move from an early LA-150 to the MkII version. Thanks

The original LA-150's can be upgraded to the MII but the hand ful of LA-100's that were converted to the 150 topology cannot. There is not enough room on the signal board to accomodate the extra tube.

Thanks Jud, hope to see you at RMAF later this month.

Thanks for the kind comments guys. We love two channel audio and hope it survives the current crunch!

Hello.
I recently got a LA100 mklll and I’m loving it. I can’t find a manual for it anywhere. I’m curious about the specs for matching it with a correct amplifier, also about these jumpers mentioned for increasing the gain. Any help would be appreciated!
