It appears as good of shape as the others I have recently sold and with good reports. As I said this is one more PALOMAR 300 out of my father\'s collection he left for me to find homes for when he passed ,as this was his love , but not mine. All I can say is that the cover is custom for better air circulation (Dad\'s idea ,and I have to agree)When turned on , all tubes light up, but as far as output , I am not knowledgeable enough to test any further for fear of damaging the amp. So I must say in good faith , it is UNTESTED &UNGUARANTEED. Thanks
