Looking for a pdf copy of PMI SSMf69PH 8DIP opamp. Analog Devices has no archived data for this IC.
It appears that this part number is an in-house type used by Musical Fidelity for the X-LPSv3 phono preamp. The MM section is the same as what is found in the later V-CAN which uses an NE5534 in place of the SSMf69PH. I looked through some old PMI datasheets and found the SSM-2134 is a replacement for the NE5534. A logical conclusion might be that the SSMf69PH is simply a rebranded/renumbered PMI (AD) SSM-2134.
