It is intended for audio frequency power amplification service in either pentode, ultralinear or triode connection and single ended or push-pull/parallel applications.The TAD EL34-STR REDBASE™ is designed to be a direct replacement for any EL34 / 6CA7 / KT77 or equivalent. Close manufacturing specification tolerances, gold wire grid, improved processing and final testing and QC at TAD in Germany provides enhanced reliability, superior sonic performance and grants overall consistency. TAD EL34-STR REDBASE™ provides electrical and audio performance very similar to that of the original Telefunken EL34.Q: When does a power tube become a Premium Selected power tube?A: All power tubes labeled Premium Selected have passed the following tests:Plate Current (PC) and Amplification (TC)Low Noise TestMicrophonic TestSonic TestsShock TestsListening TestsShorts & Leakage Tests Approximate net weightSingle versionT-EL34-RB-TAD50 g (1.76oz.)

Best Price in Bulk!

Because we are a major distributor for some products, we price very aggressively by sacrificing profit margin whenever we sell in bulk. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores. Unlike those wholesale to public membership clubs, we do not charge any membership fee. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Essentially, you are paying 10 times on shipping. We don't think that is fair to you. Why? Most of the time, shipping a 10 lb parcel does not cost 10 times of a 1 lb parcel.

Here is an example:

Opentip	Others
Product Price: $8.00	Product Price: $20.00
Shipping for quantity 1: $12.00	Shipping: FREE
Quantity: 10	Quantity: 10
Total Shipping for quantity 10: $18.00	Total Shipping: FREE
Subtotal: $98.00 Saving: $102.00 (51%)	Subtotal: $200.00

Don't be shy. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Most of the time, we will match or beat their price, and give you a credit. If we lose to a competitor, it is our shame. We then know we need to work harder in sourcing to create values for you.

* Price comparison must be based on comparable brands or models and in bulk quantity purchase.
