I purchased a Neo Planet, built by YAMASA. I purchased the machine on EBay from Pachinko Palace. The machine seems to work just fine except the reels are really noisy with a high pitched hum. Is this normal or should I contact the seller as the machine is supposed to be completely rebuilt? They are nearly so loud that they hurt my ears. The other thing is that it is supposed to have a volume control on it, does anyone know where it is located. Sorry about all of the questions as I am new to these machines and this forum also. By the way which pays out the most, the number 1 or the number 6. Thanks again as any help would be appreciated!
