I now have a transformer that is reportedly rated at 3000 volts at 1 amp. The transformer is supposedly from either a Henry or Alpha amplifier. It weighs about 70 pounds. The nomenclature is as follo

Glen, I have ECA transformers in my Henry amplifier, not sure if Alpha used them also. The plate transformer I have is an ECA1171 but the configuration sounds almost identical. Like you I had to figu

Looking at the transformer a little more, and doing some resistance measurements, I believe that you are correct. I looked closer at the wires that were cut off on terminals 6, 7, and 8. Instead of b

The Henry books for the 4k and 4ka just say "Transformer", not even their own part numbers. Get out the variac or a filament transformer and feed the primary. -- This message has been scanned for vir

Glen, If you don't find any info on the transformer hook a 12 volt filament transformer up to the primary and measure the secondary. The 3000 volt winding should read around 300 volts or so. You coul

Glen,you can tell a lot about the transformer by connecting 12vac to the primary and making some voltage checks on the secondary terminals. That will at least identify the turns ratio and presence of

Already ohmed it out. It turns out that all 5 of the threaded terminals are the secondary. Therefore, I'll probably put like 25.2 volts on the secondary and go from there. It will be a whole lot easi

Once the major winding and tap windings of the secondary are identified you can connect 120vac to the secondary and do some sleuthing of the primary terminals for more info. 73, Gerald K5GW The five

I think you can download the 3k/5k manual from BAMA and it will associate the Transformers with models. I think yours is for the 3k Classic Console Amp for Export, if I remember correctly. I can look

The 3K/5K manual is not on BAMA. There is one for the 3K/8K. In that manual there is a page that has several transformers. Unfortunately, the 1028 is not listed. It is looking like I am just going to

I found the manual for Glen. If anyone else needs it let me know and I can email it. Manual is for 3k 5k models except ultra and premier. If anyone has the premier manual, I would love to get a copy.
