Code article : YC54
6U8A - peut remplacer 7199 avec les modifications suivantes :
6U8 JAN PHILIPS SUBSTITUTION FOR 7199
7199 TUBES ARE NO LONGER IN PRODUCTION, WHICH
MEANS THEY WILL BECOME INCREASINGLY MORE
DIFFICULT TO FIND AND MORE EXPENSIVE. 6U8 JAN
PHILIPS CAN BE SUBSTITUTED FOR THE 7199 AFTER
THREE SIMPLE WIRING CHANGES ARE MADE TO THE
SOCKET. TRANSPOSE THE FOLLOWING PIN CONNECTIONS
TO USE 6U8 JAN PHILIPS IN PLACE OF 7199:
1. REMOVE CONNECTIONS FROM PIN #2. THESE WILL
BE MOVED TO PIN #6.
2. REMOVE CONNECTIONS FROM PIN #6. THESE WILL
BE MOVED TO PIN #7.
3. REMOVE CONNECTIONS FROM PIN #7. THESE WILL
BE MOVED TO PIN #2.
4. MARK THE CHASSIS TO INDICATE THAT 6U8 IS USED
IN THE CIRCUIT. A 7199 WILL NO LONGER WORK IN
THE CIRCUIT UNLESS THE MODIFICATION IS
REVERSED.
IF THE SOCKET IS MOUNTED ON A PRINTED CIRCUIT
BOARD, CUT THE APPROPRIATE CIRCUIT TRACES AND USE
WIRE JUMPERS TO MAKE THE CORRECT CONNECTIONS. |
