Updating of this web site is occurring less often then in the past. Every time windows or the anti virus are updated NM3E CANNOT be published for a few days.  So I will have stock not shown = please email to ask = and some stock shown will already be sold.

Also BIRD raised their prices for the second time this year on October 1 2020. If you take issue with this call the factory to complain. I have no control or input on list pricing.

most common question is

 "why the long connector"

The connector length is required so the attenuator can be properly mounted to a heat sink.

Meaning the heat sink should extend past the mounting block assembly by 1.25 inches for proper heat dissipation.

/\ /\ /\

Birds normal heat sink size for this item is about 19 X 11 X 4.5 inches

Prices are determined with a formula involving prior selling prices, current stock, and cosmetic condition.  

The letters in my item ID are for my reference to assure you get the correct item.   I often photograph several hundred element at a time. The only way to keep track of the element is with a unique item ID.  An item with AAA is not better or worse then an item with RRR, HHH, or ZZZ.  Nicer items of the same type are priced higher.

All elements are Guaranteed NOT DOA = Click for testing link

Stock changes quickly please verify the element is still in inventory before doing paypal.
