sears silvertone 1482 guitar amp input impedence

[muscmp]

i have a sears 1482 that has sparked on the output transformer. i took it to my tech who said that i needed to find out the input impedence on the output transformer so that i could find a replacement.
could someone supply me with this information and where to purchase one?

the amp uses 2 6v6 tubes and has the fisher 12" speaker in it. it is about 15 watts.

thanks in advance.

One of these will work just fine ......... https://taweber.powweb.com/store/041318sch.jpg

And in general, the amp has a pair of 6V6 output tubes. Then you may select from the number of transformers already on the market designed to take a pair of 6V6 and turn it into a useful speaker impedance. By their nature they will have appropriate impedances.

thanks to enzo and gr1950 for their information. i didn't realize that it was so difficult trying to get the proper info.
thanks again,

That was kinda my point, it isn't really hard. If I need a 6V6 output transformer, I don;t bother converting to impedance, I just buy a 6V6 transformer.

Imagine you need a new wheel hub for a 2004 Ford F150 pickup. You could ask someone what the lug hole spacing is and the diameter of the circle thay make and what size holes they are so we can go find a wheel hub that matches. OR we can just buy a "2004 Ford F150 wheelhub" at the parts store. We now have zero idea what all those specifications might be, but we get a wheel that fits none the less.

enzo: thanks, now i understand but when i have the manufacturer(hammond) and a retail store(tubesandmore) asking me for this information so that they can provide me with the proper one, then you try to get the correct info for them.

Hammond Mfg. - REPLACEMENT & UPGRADES - Tube Guitar Amplifier - Output Transformers

Looking down the list for 6V6 models - Fender Deluxe, so Hammond model 1750H (or 1760H if you want multiple output taps)would work, as would the smaller 1750E/1760E

I was thinking your tech should be the resourceful one here. If the seller doesn;t list SIlvertone replacement, they don;t know what you need. But it may not have occured to tech that the impedance needs of a 6V6 don;t change amp to amp. Individual amp designs might because it is not a critical measure, there is a range of values that will work fine. But tell him that any small 6V6 OT should work.

I haven't seen anyone mention secondary impedance on this thread. Are we to assume that all 12" speakers are 8 Ohms? The primary impedance is a reflection of the secondary, or load impedance, so unless the speaker in question is indeed 8 Ohms, you may have difficulty finding a suitable replacement.

Rick, those Hammonds come in two versions each. The 1750H has an 8 ohm secondary, while the 1760H has 4/8/16. And similarly the smaller E series has the same two choices.
