250EQ DIY raw kit

With or without Omeg concentric pots

• Can I use two for a stereo pair?

Yes, that's exactly how they're best utilised. They excel on mix bus and stereo sources.


• How do I buy a kit?

Just clock the "add to cart" button on the products you wish to buy. Choose the appropriate option from the drop down menu where appropriate. Then click on the view cart button at the top of the page and you'll be taken to Paypal's secure website where you can pay by your PayPal account or by credit/debit card.


• How much is shipping? Are there Paypal charges on top?

Worldwide shipping is included and also paypal charges are included in the price


• Any duties charges if I buy from abroad?

This is dependent on the country and all duties/local taxes incurred will be the buyer's responsibility.


• What do i do if it doesn't work??

Don't panic! Have a look again over your work. Look at the manual. Have a look on www.groupdiy.com at the support thread. This is a great forum specifically for audio- minded solderers! Take comfort in the fact that there's definitely a specific reason why it's not working... it's just about finding it! Definitely no magic or voodoo making it not work! No matter how much it feels like it!
