EDEN WT-300 Problems

[bassfreakah]

I have had a wt-300 for 10 + years, usually replace the tube every few years but I had a problem with low output from the pre, and just took it to a tech, he replaced an opamp in the preamp. it works perfectly now. He did some other general maintenance too. He only charged 75 dollars it was so so worth it. If you are serious about your equipment its always best if you don’t know, take it to someone who does. A small price to pay for a loyal friend (my amp) who takes care of you everynight. Just my 2 cents.

i know, i will definitely take it to service. the fact is that i have a concert in a few days, i underestimated the problem and now it is impossible for them to fix it in time. i just wanted to try something myself, like changing the tube or cleaning the jacks as suggested. can i ask you what tubes you usually use?

It may not be the tube... doing DIY repairs often leads to more damage that a qualified tech will need to address, increasing the cost of repairs.

Something super easy you could try before replacing the tube: is to preform a simple test of Patching your Effects Loop to discover if it solves your issue or not. If simply plugging a guitar cord in-between your Effects Send & Return jacks instantly solves your issue, you will have just diagnosed that the little Shunt in your Return jack simply had a poor connection causing high-resistance where it makes the connection in-between you Preamp & Poweramp sections, anytime your NOT patching an external effects device into these Effects loop jacks.

Then if this test solved your issue, you could simply leave a short angled, guitar pedal cord in place to patch the loop permanently, instead of attempting to clean or replace the defective Effects Return Jack that was causing your issue.

I've circled the little Shunt I'm referring to in this pic:
