I have used the Heath export transformers on 240 60 hz with no problem, higher
voltage but still ran cool. In fact ran a pair in parallel for large GS-35 amp.
Would be interested in buying more of them.

make it go QRO with "More Power"

Dennis the part number of the transformer you have
is for the SB-1000 export model.
So it would only support a single 3-500Z instead of a pair.
Obviously not what I thought I had.
There were a number of these sold off when Heath
went under. I do not know the meter reference
number.. The number for the SB-220 is 54-237,
SB-221 is 54-238, and SB-200 is 54-151.
Thank you Merv
Trying to remember the voltage for the exprt model
but seems to be low like 200 volts, so using it
on 220 causes a 10 percent increase in volts. Not
good for a USA replacement.
Would it have enough IRON?
I know they use 50HZ overseas instead of 60HZ.
If you are going to part with the transformers I may
be interested in one for a home brew project and
can use a buck/boost transformer to make if work on
220.
What would you be able to use it for?
I have 4 of them.
I had to use that buck boost trick myself on a Japan Radio Corp MRI amplifier
I repaired a few years back.
Also interested in a meter or two.
Were the meter numbers the correct part numbers for the SB220?
Can make
them usually work with multipliers.
If for sale please give me a price idea. thanks
very much. sorry for bother.. 73 Merv K9FD
Still trying to verify the meter part numbers before I sell any to anyone.
I really do appreciate your help.
I notice you are a K9 call.
If you are located anywhere near Frankfort, Illinois, stop over and I will
give you a free meter just for helping me determine exactly what transformers
I
have.
If you have the any spec sheets for that transformer, could you send me a
copy?
Regards,
Dennis O.
