EDCOR XPWR178 power transformer (suitable for Tubelab 300B)

Power transformer for a 120V line to 660V (330-0-330) at 200mA center tapped, 6.3V (3.15-0-3.15) at 6A center tapped and 5V (2.5-0-2.5) at 3A center tapped.
Comes with additional bare bell ends for your own customization.

Like new, used VERY briefly (under 1 hr.) for breadboarding a 300B amp.
Cost me $95 (transformer + bare bell ends + shipping) and waited over 1 month to receive.

Asking $55 + shipping
