Master room XL305 tank repair?

[outoftune]

I’m working on a Master Room XL305 output that has dead tank on channel two.

I’ve measure the resistance at the output of both tanks, the good one is 48ohms and the bad channel is reading 0ohms.

Does anyone know if it’s possible to repair what’s inside the tank? and if so is there a procedure to open the tank for repair?

Sounds like you have a short somewhere, investigate further. If the tank was faulty it would probably go open circuiit.

I think you'll need to drill open the rivets holding the two case halves together.

Once you do that it's repairable with Accutronics/Bell parts. Odd for the receiving transducer to short.

Not related to the short but you'll likely find some degraded foam.

thank you so much i'll take a look and try that.

Inside the "tank" you'll find Accutronics Type 3 sleds.
You can buy replacements at CE Distribution if it turns out you need one. https://www.cedist.com/products/reverb_tanks
Super odd that a receive transducer would short.
