It show in a more simply diagram eg: TB1(1-10) TB2(1-10) to wire the primary circuit for different voltage. Tim In the schematic the primaries of the transformer are wired in parallel, they need to wired in series.

Link for Altec9444A: And Transformers/power Amps/9444A Power Amplifier But the Altec 9442A manual does not show the same type of simply diagram as in 9444A.:( I had ring a local shop for help in re-strapping the primary circuit to 240v but was told that will charge between 80-100 dollar for the service and owner must provide a schematic. If I had the amp in front of me it would take about 10 min to do. so the primary transformer is wire for 110v operation voltage.


Hi all, I just purchase a Altec 9442A anniversary edition and a Altec 9444a power amp. Can anyone Please hht to me on how to wire the main transformer input to accept 220v or 240v? Tim Thank you for sending me the link to the manual for Altec 9442A , But due to lack of knowledge in reading schematic diagram.
