I was lucky that the original output transformers were in great shape. The power transformer, not so much. The power transformer was rebuilt by Heyboer.That's a beauty, well done! I have two HF-87's, both are in need of one output transformer though in order to restore them. And they are two different makes of transformers, so I'm always searching for some.
I most likely will have to go that route, it's very hard finding correct parts for them.I was lucky that the original output transformers were in great shape. The power transformer, not so much. The power transformer was rebuilt by Heyboer.
I can't confirm the original manufacturer of the output transformers but I highly recommend Heyboer to have them built if needed. If they are the original manufacturer then they may also have the original specs.
Thanks for checkingNot the same size . Sorry
Blackdog, you are super lucky to have an 81 in that condition, it's nice!I’ve had several EICO pieces over the years but sold them off. Got this 81 about six months ago and got it going yesterday. Great sounding amp! Not the best picture but it’s in great condition.View attachment 1827504
