Referral Program

In order to promote our products and let more people know about J&K Audio Design products, we are offering a special "Referral Program" where existing customers can recommend J&K Audio Design products to their friends, or even strangers and get a commission.

Terms & Conditions
  • Commissions - apply to 2 tiers only.
    • 5% commission for direct referees.
    • 2.5% commission for your referee's referees if your referees decided to be a referrer too.
    • Referees get a discount of 2.5% if they quote a valid referrer. 
  • Discount applies for first purchase only. Subsequent purchases do not apply.
  • Registration is required if you are interested to become a referrer for our database upkeep purposes.
    • Please provide us your full name, PayPal account, and past purchase proof.
  • Offer is valid only for customers that has bought products from us previously, irregardless of the purchase date. 
    • We only want referrers that have used our products and know that our products are good and worthy to recommend to other users.
  • This offer is for a limited period only. We reserve the right to stop the program at anytime. We have yet to determine the cut-off date.
  • Unlimited referrals apply as long as customers quote your full name, and/or email that we can track in our referrer database.

Hope you can make full use of this special program we are offering, while it lasts.This could be a little perk that helps you get more funds for your next audio gadgets purchase!

Some tips:
  • Talk more about our products.
  • Share the pictures with your friends and family.
  • Post your projects at various online forums and talk about it.
  • Socialize it - mention us in your Twitter, Facebook, or any social platforms!
  • Tell your friends that if they quote your name, they get a 2.5% discount from us!
  • Present your projects in your blogs, your website, or anywhere that could generate traffic!

It may not be much at first look but it does add up significantly if you could generate a lot of referrals without actually doing much or manufacturers a product.

Example: 
  • If 1 referee buys U$500 worth of products, which is pretty common nowadays for a single order, you get U$25! 
  • If 10 referees buys U$500 worth of products, you are getting U$250 commission for very little effort! 
  • And, the above is automatic if your promotion method is permanent - blogs, forums or websites that can be found by search engines or have a lot of traffic! 
  • If you have multiple referees and your referees have multiple referees themselves, you are looking at very handsome returns! 
    • Continuation of the above, if the 10 referees have 10 referees that buy U$500 worth of products, the 1st referrer is going to get
      • U$250 (from 10 referees) + U$125 x 10 (from 10 referee's 10 referees) = U$1500
    • Now this is where things start to get interesting.

Silver Output Transformer

Story of a pair of silver output transformers
Precision CNC Crafted Fiber Glass Bobbin
Wind, wind and wind...
Nice and shiny LEWCOS silver plated magnet wires
Wires are properly aligned for maximum coupling and durability
Measurements to ensure proper matching
It's matched alright... down to 0.x Ohms - 0.3%!
Stray Capacitance
Leakage inductance
Primary inductance - gapped at 110mA for 300B-XLS
Primary inductance - gapped at 110mA for 300B-XLS - 2% tolerance!

Potted, 3.5K Primary, 40 Ohm secondary - for headphone use
Direct draw of magnet wire to the binding posts for direct signal path

Transformer cover - 1.2mm thick top cover, 1.8mm base plate.

Extra piece of brand new cover for user to pot his power transformer.
1st layer of packaging - shrink wrapped, covered with thick paper box, and protected by bubble wrap before being boxed in the 1st box.
View before bubble wrap is added.
2nd box!
Hope you enjoyed the show!
