Hi erzane, I happen to have my NAC disassembled here in my office so I snapped a few photos. Let me know if this helps

Trying to deal with this myself as I clean up my astro city cabinets. I’ve done my best to clean them up but there is still a lot of stubborn rust that I can’t get off without resorting to something more abrasive. I don’t want to use something abrasive if it’s going to remove the chrome...

My STV kicked the bucket this week and I simply don't have the time or patience to attempt to repair it, so I'm in the market for a new, working main board. Please PM if you've got one for sale.

I'd like one of these @Mitsurugi-w 👍🏻

I'm in for one of these

If anybody else has a RFJ board and could try running it without the Z80, I’d be interested to know whether it freezes for you at this exact spot as it does for me. Just turn it on and let the attract mode run for a minute without pressing anything. For me this is consistent.

I tried replacing the Z80 with a Zilog Z84C0020PEC that I had lying around. I looked up the data sheet and (if I’m reading it correctly) it should be compatible. The MAME notes that it should run at roughly 4.9mhz...

Thank you, this gives me a lot to go on. I think I may have a spare Z80 sitting around from my Donkey Kong’s high score save kit. I may swap that in just to see what happens. Another thing that may be noteworthy is that “reset button” near the oscillator does absolutely nothing. I used my...

@ic3b4ll I have a Raiden Fighters Jet board (same one as OP, I think) which is exhibiting a similar problem. I will turn it on and it will operate fine for about a minute and then freeze. (sound is also missing, but I’m just focusing on one problem at a time) I’ve cleaned and re-seated the...

Nevermind, I seem to have found the answer to my question in another thread. Apparently the 400-5198-01 is identical to the 400-5198-01X which has been documented and appears to have a cap kit on arcadepartsandrepair.com...

I’ve got a 400-5198-01 PSU (which I presume is just a later revision of the 400-5198 ). Do you happen to know if the capacitor list is the same? If not, has anybody mapped this one out?

Has anybody in here successfully removed a bonded yoke from a consumer tube and replaced it with a yoke from an arcade monitor? I have two JVC 27” consumer sets with beautiful pictures and a high-TVL count that I would love to throw into an Astro City if possible, but the yoke impedance is way...

Is there anything else I should worry about when swapping in a chassis that was originally not paired with my tube? For instance, on the arcade-otaku wiki it mentions that there's a different value capacitor on the neck board depending on whether it was installed with a Toshiba or Matsushita...

I've got a PD1843 chassis in my New Net City Toshiba PF and I'm currently looking at buying a spare in case this one ever dies on me. I found somebody willing to sell me a PD2367 chassis. It looks like most of the numbers here match, but it seems the vertical impedance is off by about 20%...

I’m hoping to order some reproduction Astro City panels. I’ve heard @alberto1225 does good work but I’m not sure if he’s got a website or how he prefers to be contacted, so I’m just posting here. Looking for 2x 2L12B panels and 1x 1L12B panel (plus one 1L12B New Net City panel if possible)
