Description
Our Small Bottle Rectifier!
The rectifier tube for smaller vintage amps like the 5F1 Fender Tweed Champ or the Tweed Deluxe 5E3 if more headroom is required.
Higher output voltage than the 5Y3WGTB (RT513).
Not suitable for the Mesa Boogie Lonestar Special due to the higher output voltage.
Please use the S5Y3 for this purpose!
note: Unfortunately, our current stock of RT503s has a slightly skewed mounting in the base. This does not affect the functionality of the tube in any way, but if a straight appearance is important, please use another product.
