Delivery time

international shipping takes 5-8 days. If it takes longer than 14 days often a delay because of customs can be the cause if your destination country is not in the EU.



Track your shippment

Insured packages and letters have a tracking number which can be tracked on our shipping partners website www.dhl.de
or www.deutsche-post.de. Most often the international tracking information ends in Germany with the information "The package was delivered to the destination country, please use your local shipping company to track the package" which means the package will arrive soon and was hand over to your local shipping company. If your local shipping company support tracking, use your tracking code on the partners website.

A WSM has a maximum of 15VRMS input, a XSM has a maximum of 50 VRMS input, otherwise they have the same performance. 
WSM and XSM are not gapped for DC.


Too much power issue with the G-Pultec Mono project

If you get to much power or to less from the power trafo it can have several reasons.
The trafo secondary value for example 220v/0,1A has a Uo Value of 248V which means without load. If you have tolerances measured without load it can be caused by under-/overrated mains or tolerances by the measuring tool. The trafos perform 220v on a load of 0,1A. If you have too much voltages you can regulate the voltage with resistors which are able to take this much current.
Less load means the voltages goes a little bit up and more voltage will destroy the transformator. It will get hot, melt and short.
Some people have this "too much voltage" issue with the g-pultec project. If you build a mono-project please swap the 3k3 resistor to an 18k 10w resistor come down to 250v on the tubestage.
