tranny serial's..

[Shep]

i had to pull my mk out of it's rack mount the other day and i notice some werid ( to me ) serial number's on the output and power transformer's..

power.. 561110/Ela606-122

output...562004/Ela606-120

does that sound normal..


Thanks TOm

Looks like a pair of 1991 transformers. The 561110 is the export power and the 562004 is the MK IV and later MK III Simul-Class.

The earliest schematic I have is 8/92 where the export power transformer
is 561137. Your's may be the original part number for a 91.

well. it's out of my 7/91 mk iv...BUt it's running US power and there is no other coil tap..wats the export power transformer feature?...


thanks tom

Multiple taps for world wide voltages.

I will see if I can track down where that PT came from.

i took it to a tech who had a look and said there were tap's but the schematic for it said it was for the tweed power..?? i was a little funny about that becasue aren't the tween tap's wired in?


i would love to run it AUS 240v...can it be done?..

PT?

Thanks BB tom..

The MK IV's use same power transformer used on the DR's and Tremoverbs.Most of them have a 5V rectifier heater tap that is taped off and not used.

I still have not found any Mesa PT with that part number. If it were an export, it would have at least 4 to 6 taps, or just one @ 240V. Mesa really stopped using the switchable export with the 6 taps with the MK III.

it's a strange one.... so you are saying it's a got theexport tranny's serial # but it doesn't have the tap's...?


Thanks tom

No, I am assuming it was an export as you are down under.
The earliest export tranny numbers I can find are561137 and 561141.
