WELBORNE LABS TECHNICAL SUPPORT

Need help with a Welborne Labs product?  Send us an e-mail to: techsupport1 @ welbornelabs.com   Please state the problem you are having, symptoms, etc.

You can help us to reduce our workload if you will take the time to perform your own troubleshooting prior to contacting us.  Did you build the kit yourself?  If the answer is yes, go back and take some voltage measurements outlined in the assembly manual.  This might tell you where the problem is.  Did you try swapping tubes from one channel to the other?  This will provide an indication as to whether or not it is a tube problem or an equipment problem.  If the problem follows the tube, then it is a tube problem.  If the problem stays in the suspect channel, then it is an equipment problem.

And finally, please limit your technical queries to our products or products we sell.  We receive over 50 e-mails per day and a good percentage of them do not even apply to our product line.  If you want to know how old your Marantz amplifier is, please ask somebody else.  If you want to know if we sell motorized volume controls, look on our website first...do you see any, if not, that means we don't sell them?

Please help us to better serve you.  Thanks for your support.
