Direct Replacement / Substitute / High Performance Upgrade for the RC4739, uA739 and MC1303 Dual Op-Amps
MADE IN USA
This Drop In Board is a direct replacement and upgrade for the two RC4739 Op-Amps in the
AEG Telefunken M15 / M15A Playback Amplifier BC-WV1 ( Wiedergabe Verstärker BC-WV1 ), Record Amplifier BC-AV1 ( Aufnahme Verstärker BC-WV1 ), Phase Linear 2000 Series II (Phono Pre-Amp + Output Driver)
and
will substantially lower the noise floor, improve distortion and give
you more output power to drive 40 to 600 Ohm Inputs without a
transformer, eliminating impedance mismatches.
This unit will enhance any Equipment in performance which utilizes the RC4739, uA739 and MC1303!
This Drop In Board will work for any replacement of a RC4739. The RC4739 did not utilize any type of compensation, only IN+, IN- and Out of its OP Amps.
The only exception would be when replacing a uA739 and PINS 2 OUT LAG A; 3+4 IN LAG A; 10+11 IN LAG B, 12 OUT LAG B are used in your circuit - Please contact us before purchasing if you are not sure if this replacement board is going to work for you.
Our Drop In Circuit Board contains the standard Audio OP AMP NE5532A (High Grade Version)
from Ti and can be directly soldered into the RC4739 location on the
Printed Circuit Board or just inserted into a 14 PIN DIP Socket if the
PCB has a such a socket.
The Device is fully Pin compatible and exceeds the original maximum Operating Voltage of the RC4739, uA739 and MC1303!
(Note: see above partial PIN compatibility with uA739 which depends on the circuit the device is used in)
The replacement is therefor easy and hassle free.
The Pins are Gold Plated and the entire assembly is PB-Free (Europe)
