Thermionic---So much info in so little space! But I do thank you for your post---really is a lot easier to find the same sizes---especially for intergrate or recievers---too much stuff under there!!---now I am learning that not all caps have to been connected red /black---or hot/cold----but have to be careflul as there are several that have very small arrows telling the direction of the install---and I gave up golf for a relaxing hobby??? Now I know I can justify more than one system! JD
