RARE SIEMENS WEST GERMANY
ECF802 RARE MUNICH TUBE
Rarest SIEMENS HALSKE Germany 1961 Munich Production
Upgrade your 6U8 APPLICATION to QUIET LOW NOISE SIEMENS ECF802!
VINTAGE NOS 47 YEAR OLD TUBES!
..."You can use 6U8 – 6KD8 – 6GH8 – ECF82 – ECF802 , all have same pin out (may be others), they do have different parameters and may need a tweak in the demultiplex for best separation. None of them will cause a problem in the preamp stage though the resulting sound may change."...
Proven substitute for Superior Performance in your McIntosh MR-67 and other tuners and some amps that accept 6U8 / ECF82 / 6EA8
In reference to using ECF802 as a 6JW8 ECF82 / 6U8 / 6JW8 / 6GH8 substitute: "... ECF802 in comparison is almost the hyper version - everything turned to live and colorful, the improvement is so huge on my highly modified Scott 299D, which IS better than almost 99% of tube amps I have had and heard (very surprise here too consider the Scott is a product of many decades ago and versus these latest 4-5 digit "HI END" machines made today). My Scott is much like a fully waken up lion. This is a truly low noise, low mircophonics, and audiophile grade tube. Although the tube is not rated exactly to the ECF82 and 6U8, but It can be USES for DIRECT SUBSTITUTE safely. What a shame to those who have these but don't know it could be used. These are also the best tube I ever tried on my beloved Scott, period...." -derstarmb ( 367

These Siemens & Halske are the MOST SCARCE of the ECF802 construction for superior performance
For 6U8 application performance Upgrades.
"...I have been using ECF802 in place of my regular 6u8 in my McIntosh MR-67 tuner for years now, and the vast improvement is immediatly noticable ..I would never go back! It's as if the MAC was really designed around these tubes but due to the factory closing & cease in production, and due many things not limited to the high cost production the 6U8 was reluctantly substituted. All I know is that when I swap back and forth with the ECF802 to the 6U8, as the manual calls for, the increased improvement and "scary" performance of the ECF802 is the compelling reason why I will not use any thing else but these..."

Just like an ECC803S is an upgrade to the ECC83, the ECC802S to the ECC82, and the ECC801S to the ECC81, the ECF802 is a formidable upgrade to the ECF82/6U8A:

ECF82 / 6U8A / CV9858

The ECF82 is the European number for the American 6U8A with the same pin out and nearly identical specs as the ECF802:
Heater Voltage ............................... 6.3 V
Heater Current ............... 0.45 A

Since the 7199 tube is not made any more and as the remaining supply of these tubes slowly dries up, these wire modifications and 7199 to 6U8 adapters will become more common.
SIEMENS HALSKE 6U8 CAN BE SUBSTITUTED FOR THE 7199 AFTER THESE 3 SIMPLE WIRE SWAPS ARE MADE TO THE SOCKETS.
In the past, manufacturers often substituted the now more expensive and rare 7199 for the presentlyavailable 6U8, 6U8A, 6GH8, 6GH8A, or 6BL8. 7199 and 6U8, 6U8A, 6GH8, 6GH8A, or 6BL8 tube types are not pinout compatible, because their triode sections are not pinned in the same order.
Modification converting 7199 to 6U8 Phase Splitters with a simple re-wiring of the 7199 socket in 3 easy steps; TO USE THE SIEMENS HALSKE 6U8 IN PLACE OF 7199 perform the following:
Step 2: Disconnect Control Grid Pin 7 and rewire to Pin 2
