Hi Victor, I'm confirming my pre-order. Just send me an invoice when you're ready and I'll pay through PayPal.

Good to know the preamp is rolling already! I asked Elekit last week and by the reply I got they were still not sure which day/if they would be available to ship this week. Though Im not sure they were referring to the 8550 or the 8900, which was backordered
Part 2 from Sunvalley

Thank you Victor. What a nice review and careful build explanation. We can see he highly regarded the 8550 and the upgrade with the Arizona caps. In their website I could see there are many options and suboptions for the capacitors, I wouldnt even know which to order. maybe There are other cap upgrades tested with this preamp?
I use the following site as a reference on my Crossover and Audio upgrades.

Will be starting the TU-8550 build this weekend. Will be using the JJ's for burn-in but will be moving to Genalex or NOS as I need to feel out the Pre-Amp. I will be using the following Upgraded parts:
Films: Mundorf Supreme - Silver Oil or Arizona Blue Cactus 0.47uf
Resistors: Precision Resistive Products
Films: Mundorf Supreme - Silver Oil or Arizona Blue Cactus 0.47uf

Hi Cohiba,
How did the build go so far? Wondering how you chose which caps to use.
I was able to source 0.1uf caps for the 8900 locally but not the caps for the pre so far.

I use these 2 sites for the better parts https://www.partsconnexion.com/ and https://www.hificollective.co.uk/
Thread #53 has a site that I use as a guide which helps in factoring Films. I also have used Arizona, Auricap XO, Mundorf and many others in Speakers,
Audio gear on recapping or building kits. Space is a factor for the TU-8550 with Films and make sure to look at the docs for sizing.
Thank You Victor and the TU-8550 sounds wonderful with a Huge Sound Stage (Mundorf Supreme Silver/Oil) with a
Clean background. I had to add the Cooper shield strips as my PC's WiFi was interfering with the Right Channel.
