Yamaha YC-25D Combo Organ Supplementary Service Manual, MPC1000 repaired, A 3 part interview on Newgrounds.com (my longest and most detailed interview to date!), last week's Patreon rewards for the $1 patrons: Jabun's Daydream album + more updates!

Hi everyone and hope you're having a good week! It's been a busy one here at JabunAudio, though my motivation is definitely wavering due to the coronavirus lockdown situation I'm currently stuck in... I've been taking a bit of a music break to do some maintenance work including replacing the sticky buttons on my MPC1000 which seems much happier now! The new buttons are a little stiffer than the old ones, but they work at least which is the main thing! I've also taken the time to finish drawing up a supplementary service manual for my vintage Yamaha YC-25D combo organ + there's more rewards for the $1 patrons to share today, as well as my longest interview to date with The Interviewer on Newgrounds.com! Let's start with that service manual!

As many of you already know, I'm currently fixing up a vintage Yamaha YC-25D Combo Organ and after being unable to find a service manual for it online (not even to buy...), I decided to put together my own YC-25D supplementary service manual (to be used in conjunction with the freely available YC-45D service manual) to help in problem solving and repairs. I figured there was no point keeping it to myself so I'm giving it out free to anyone who needs it as a thanks to the community for their help so far. Use at your own risk and share it with anyone who needs it, but please don't charge for it. If you do find it useful though, feel free to make a Paypal donation. All the details are in the document's foreword. Happy YC-25D organ repairs. Download below:

Since I posted it earlier this week, my homemade service manual has already been featured on the amazing all things combo-organ website combo-organ.com too! Thanks to Robert for the kind words and sharing my work and hope it's a help to your readers!

Updates on my own repairs: I'm still trying to source that final component (an LM3211 or equivalent frequency divider IC), and hopefully I'll have some more concrete updates on that soon! Fingers crossed!

Next this week, I've got something super special to share with you today and something I hope you enjoy! Last month I took part in my biggest and most detailed interview to date, a 3 part discussion with The Interviewer on Newgrounds.com all about my musical journey so far! It goes right back to my musical roots, through many of my notable projects including collaborations, bands from my teen years and beyond, through to my solo projects Better Than The Book and Jabun, discussing great memories, not so great ones and my advice for musicians and creators from my own experience. It's a long journey, but I hope you get something out of it and enjoy the read! A huge thanks to The Interviewer (The-Great-One) for inviting me to take part in this, and I'd like to share some of his kind words before you read:

"Today's guest is quite possibly one of if not the hardest working musician here on Newgrounds. With his project Better Than The Book being a success here on Newgrounds and acclaim for his assistance towards other musicians here on the site. His skills are incredible as a composer, lyricist, singer, and guitarist. His story is long, but an amazing one and I wish for you to read it all the way to the end. I am most pleased to welcome, @Jabun."

"Jabun is a rare talent that you don't see in too many musicians nowadays. He is a musician of many hats which is what a lot of musicians used to be like. His songs are not factory produced by writers who are looking for that zany lyric or melody that will stick in people's minds. He makes music that not only he likes, but he thinks people will like. He is truly one of the best here on the site. I know this interview was in three parts, it is the longest interview I have done to date, and I felt it needed to be. Jabun's story needed to be told and I wanted you to experience the journey in hopes that it would inspire you. If you're a musician just starting out, I hope you learned something today and will take it with you."

Without further wait, I hope you enjoy the ride! Read the full interview below:

Part 2: https://theinterviewer.newgrounds.com/news/post/1119986
Part 3: https://theinterviewer.newgrounds.com/news/post/1119990

Next and finally this week, yesterday was the first Wednesday of the month and so last week's Patreon rewards are now available for the $1 patrons (mp3s and artwork only). This month we arrive at the final entry in the Jabun discography (so far), Jabun's debut album Daydream! Read more and grab the rewards below:

$1 rewards: https://www.patreon.com/posts/40080120/

And that wraps things up for this blog post! There are some collaborations potentially brewing in the pipeline so hopefully that'll get me a bit more motivated, and hopefully I'll have some updates on those organ repairs to share next time too! We shall see, and until then I hope you have a great week whatever you're up to and thanks as always for supporting JabunAudio and my various projects however you can! Stay safe, take care, and see you around for the next one!

Hi there. Tripped across your site while searching for information relative to my Yamaha YC-25D Combo Organ. Since you have been refurbishing yours can you tell me, how do you open the hood on one of these? I cannot figure it out though I have seen pictures of it open and the circuits exposed. I appreciate any help you can provide.
Thanks!

Hi Richard and thanks for getting in touch,

On the underside of the organ if you're in playing position facing the keyboards, there are 3 pairs of large cross-head screws on the left and right sides of the case, roughly in line with the edges of the top panel, upper keyboard and lower keyboard.

If you first undo the furthest screw back on either side, that'll free the lid to open up and expose the majority of the electronics.

Undoing the next closest pair (if necessary) will allow you to swing the upper keyboard up to check out the circuits on the underside of that. I found it helpful to swing the upper keyboard up to stop wires getting stuck if removing boards from the main circuit rack as well (especially the ones with lots of wires).

Undoing the closest pair will allow you to swing the lower keyboard up similarly.

Each of the pairs of screws are a different length if I remember correctly so be careful not to mix them up, and they need to be taken out / put back in in that order as well (top -> upper -> lower for removing, and reverse for putting back).

Hope that helps, let me know if you have any further questions and all the best with your servicing!

All the best,

Nick
