Displaying Photos for the Repair of a
Ampex ATR 102
This lovely 1 inch 2 track machine caught fire in a studio and filled the building with accrid smoke.
The Capstan Motor went into hyper-drive and frightened the owner to bits.
Under the top panel - good old 2N3055 power transistors shorted out.
Bad design from Ampex!
The 3055 Emmitter Resistors were hiding right in the middle of the machine - huge wirewounds which you cannot
get to without removing 50% of the machine.
The wirewounds had got hot when the transistors went short and burnt the loom close by!!
Seperately, 2 cracked resistors were spotted and replaced along with some big old
R22 0.1R resistors which looked 'Cooked'.
Once I found out how to 'Engage' the machine with the tape loaded - a soak test
and wonderful sounds - All OK now.
The owner has agreed to have a full Re-Cap and Setup later-on (he is too busy using it at the moment)
which will be featured here as and when.
