So I finally got around to upgrading the speakers in my Tommy today. I am still supposed to be taking it easy, so I had my tech Gavin install them for me (it took him about ten minutes, probably would have taken me an hour). My machine already had a Pinball Pro sub, so we only replaced the backbox speakers. Overall, I'm happy with the results. The difference didn't blow me away, but the new speakers definitely sound better than the stock ones. There probably would have been a much greater impact if I was also adding the sub at the same time. One nice thing is that the dreaded Data East hum seems to be slightly softer with the new speakers.
While he was over, I asked Gavin if there was anything he could do to make the auto launcher perform better. Balls were sometimes not even making it all the way out of the shooter lane. He said that the older Data East/Sega auto launch kicker assemblies were a terrible design, and the best thing to do would be to replace it with one of the newer Stern types. Fortunately, he had one on hand, and he proceeded to swap it out. HOLY CRAP what a difference it made. The new auto launcher works perfectly every time, fires the ball much harder, and is 10,000 times better than the original. I highly recommend this upgrade to anyone with a qualifying machine. In my eyes, it's an absolute must. Here's a link to the part:
By the way, if anyone in the greater Chicago area is looking for someone to fix their machines, Gavin Miller is the best in the business. The guy's pin knowledge is truly unbelievable. He also does video game repair. Here's a link to his site:
