Hi all the inlaws have a very old Toshiba microwave and the bulb has gone, major catastrophe for the elderly, Its model is ER-582ET the bulb is a screw in type but is bigger than the current type can anyone help please?
thanks
In that case it is probably an E17 thread size which fits with your 16.5mm measurement. Could it be one of then ? Hope it is 🙂 I have to say I have not come across that size before!!
