Good Single Ended Audio Output Transformer

One must be a good catcher as a good pitcher.In other words fix your receivers audio. De-hnyellaphying receiver audio is much easier than fixing up a vintage AM transmitter. BUT the one limiting factor is the audio output transformer. Most of the vintage receivers have single ended output stages .6AQ5 ,6V6, 6K6 etc. Gone are the days of finding some junk vacuuuum toob color TV set that could yield a good audio output transformer. The limiting factor is the inductance value of the primary as well as the amount of core material there is as well as the maximum DC current rating of the transformer. It seems as though the only commonly available transformer manufacturer is Hammond. The offer a high end line of audiophool grade single ended transformers that would work extremely well if you could fit it on to the chassis of your receiver. They are very pricey as well.But very good. At the other end of the spectrum are the replacement grade single ended transformers. There are some fairly substantial pieces as well. They are very good as well, but lack inductance.Hammond used to spec the inductance values in their older literature. They don't now. They just post a frequency response spec. This is very dependent on may factors. One thought was to buy one of their larger replacement transformers ,the125 ESE This is rated for 80 MA dc in the primary but only an inductance of about 5Hy. You could open up the transformer and separate the E and I lamination blocks and greatly pare down the thickness of the core gap spacer. It would be a lot of work to get it right. I dug deeper and found that Hammond has a whole line of guitar amplifier replacement transformers. There were very few single ended transformers available. BUT I found one that might work very well. This is the 1760-C. It is rated at 5 watts. It is definitely larger than a replacement single ended transformer . The transformer is 8K primary with a tap at 5K . One could easily connect the 8 k lead to the B+ .the 5K lead to the screen . I believe it would work well as a single ended ultra linear stage. The total primary inductance is 23Hy. This is decent. The maximum DC current was not specified. I did email Hammond and got a prompt response. It is 40 Ma. I see this is a perfect replacement for many receivers. I will have to buy one and try it out. If the audio section of the receiver is reworked with the appropriate component values with negative feedback,your receivers audio would be hard to beat.
