Ive had this thing and a few others for years and completely forgot I had them and this one I thought abought and remembered lastnight so I ran out today and dug it out to take a picture.

I hooked it up again and this thing really works good and with 12-15 watts input drive I was seeing just under 400 watts out on a peak reading meter. Its nice amplifier it runs 4 x MRF-492 Transistors which I honestly am not familiar with this particular Motorola output transistor.

I am thinking its a Grey base do to GB on the faceplate but if anyone knows forsure and can correct me any info would be greatly appreciated. Yes I know its dusty and needs a bath but one thing at a time here people LMAO!!

Im pretty sure its a Gray due to the build and transistors they used. I remember hearing that Gray base amplifier models all started with "GB" I just wanted confirmation or someone to say they have seen one like this LOL!!!
 
My GB 150 has the same knobs , switches an led's except its black w/ silver front an the top is also a heat sink ! It has been faithful for years but I sure am liking that 300 an red is my favorite color ! lol

Bashed for trying to rip someone off. I think there's some relevance here.
