The parts come from my collection that I have accumulated over the years. For sale I have a professionally made adapter from one ELL80 tube on two EL95. This is my authory project - I didn't copy anyone. Adapter dimensions: 24x38x20mm. Its height with EL95 tubes mounted is 75mm (without pins). For comparison, the height of the ELL80 tube is 70mm.
You won't find the cheapest offer anywhere in the world, even from a Chinese, I assure you.
The offer is for ONE adapter without the tubes EL95 visible in the photo.
