Bought my first home pinball machine. TNA Number 512 and received it a couple of weeks ago.
First off, props to Danesi Designs and Spooky for this excellent game! Love the simple-but-difficult rules/layout, the overall game aesthetic, beautiful lighting, and use of sound.
Melt Down Mirrors
Knocker (disabled for neighbors)
Speaker Lights / Grill Covers
This was pretty severe. I did as brenna98 mentioned and the super lube from pinballlife did the trick. It still makes noise as I believe was intended, but the rattle I was experiencing sounded like it was either destroying itself or grinding coffee.
Power Supply Fan Replacement
My fan was extremely loud. Maybe I noticed this more than most people because of my hard wood floors and lack of anything next to my machine.
I bought the fan mentioned by borgdog and replaced the fan in the power supply. Very happy with the results and the price of this fix.
Light Diffusers (ledocd)
These are great. Without the diffuser, the direct view of the leds was kind of distracting.
Beacon LED upgrade
Used the same nimblepin mentioned, the cointaker 13 led 89 bulb in red. As mentioned, I can see the individual LEDs but overall I'm happy with it as is. A 3d printed diffuser would be an improvement.
Rail lights (hooked on pinball)
I just installed these. I think they look pretty slick. A word of warning though for people particular about idle noise. The inverter has a knob that lets you adjust the AC frequency from 600hz-1200hz. If you can still hear high frequencies (should diminish with age), the hum can be a bit much in a quiet environment while not playing. I found that turning it down to the lowest setting (600hz) was worth the decrease in brightness. After researching on the net some, I found some suggestions of putting hot glue around the transformer. I did this and it did help reduce the noise coming from the inverter to a more tolerable level. There is still a hum coming from the actual lamps. I'll post more information if anyone is curious if/when I find any solution.
Pin-Butts High Gloss Polyurethane Leg Leveler Caster (pinballlife)
No longer marks up my wood floors.
LCD Display Upgrade - work in progress
Following what audihere said, I purchased a display and matching controller. I was hoping to purchase an IPS screen for larger viewing angle and ended up getting a display that had different mounting that wasn't going to work. I think I figured out what model to buy by searching panelook
I did not find how to purchase one of the 4 listed (if you further restrict to IPS). I'm currently waiting on my N156HGE-L11 (non-IPS) and compatible controller to be delivered. Hopefully, this will work out.
Speaker Noise - work in progress
Looking to reduce the hum coming from my speakers when idle (increased noise after EL lighting). I was hoping to use some cheap hdmi spdif audio extractor to keep it digital to just before the amp input, but have been unsuccessful so far. I tried two models vhd-h2hsa and one from a company called Onvian. They seem to work on all my other hdmi devices, but not the hdmi output from the TNA board. Anyone know why this would be the case? Maybe this could be alternatively solved by increasing the sound output level from the display controller and decreasing the amp levels or maybe some cable changes or cable routing?
I really appreciate the posts this community has made. I've learned a lot and have increased confidence in caring for my machine. Thanks everyone!
