Service Repair

Please read before returning any product.
All products returned for service or update from customers must have the Service Request Authorization Number written on the outside of the shipping carton. The Service Request Authorization number is obtained by filling out the Service Request Form. Write to us to obtain Service Request Form at service@zweimann.pl . Upon successful submission of the form, we will email S R A Number. Please write this number on the outside of your shipping carton.
Dealers or distributors needing service should email service@zweimann.pl to receive their Service Request Form. ZWEIMANN will refuse to repair any product that has been modified.

For warranty service, a copy of the dated proof of purchase from an authorized ZWEIMANN dealer must accompany the Service Request Form. Only new products purchased through an authorized ZWEIMANN retailer or importer are eligible for warranty coverage.

The basic labor rate for non-warranty service work performed at ZWEIMANN is 130:- Euro per hour. A minimum one-hour charge is normally applied to diagnostic service evaluations.

All vacuum-tube products sent to the factory for service or update must be accompanied by a full complement of tubes (remove tubes and pack securely before shipping) in order to fully evaluate and test the unit’s performance. Exceptions are units returned for complete retubing or units returned for update that includes all new tubes.

Should replacement vacuum tubes be required to complete a repair or update, only ZWEIMANN tubes will be installed in order to assure product performance and to validate the 90-Day Limited Service Warranty.

If a customer refuses the use of ZWEIMANN parts and/or tubes needed to complete a repair or update; the product will be returned unrepaired at the owner’s expense.

ZWEIMANN only performs factory authorized service and currently-available updates. Custom modifications will not be performed.

The customer sending in the unit pays round-trip shipping on all non-warranty service and updates, and is solely responsible for payment of any charges. Second-party payment is not permitted. Information about a service unit is only available to the customer sending it in, not to second parties.
