The YARRA Preamplifier/HPA for Melbourne DB Group Buy

Jump to Latest
#41
I am trying to gauge interest in a GB for a fully machined case for the Yarra with all holes and cutouts factory made by Hifi2000. The more people participate, the lower the cost to spread a custom machining run for these cases. The Yarra is a special preamp/HPA. Possibly one of the best ones you will ever hear or need and that is why I want to put it in a nice professionally made case.

Can we start a signup sheet of potential interest? I don't want to start a whole new thread, but we can make a separate list. I have no idea on what it will cost - but a price under $250 is one guess. I am hoping with enough people we can get this at the $150 level - we will see once JPS64 gets a quote.

How many people are interested in having an integral 1/4in TRS headphone jack on front panel? We also need power switch push button and LED. The preamp boards may need to slide back a little to make room for panel jacks etc. JP will do the 3D CAD drawings on SolidWorks and then generate production drawings for submitting to vendor for price quotation. I am just taking a WAG at the price btw. But I bet the more people we have the more we can share the one time setup fee.

I am interested in the custom case, butwould prefer not to have a headphone jack on the front. I rarely use headphones, and already have a dedicated HPA just in case.

2U is big enough to accommodate a thermally controlled fan. You can implement "N" different temperature sensors, sprinkled throughout the chassis, and draw up whatever temperature-versus-fanspeed% curve your heart desires. Feed everything into a 14 pin uC (if you've got a large number N of temp sensors), or an 8 pin uC if N is a reasonable integer. Presto, a fan whose speed (and noise!) does exactly what YOU want it to do, versus temperature. I did one of these for a Unix workstation in the late 80s (discrete parts, no uCs!) and end users liked it a whole lot. Modernized and weaponized, it would be damn delightful to many buyers (I predict).

I don't need the case, but wanted to update mine to include the two Melbourne DBs.

GB status update. I edited the list to standardize the numbering by calling the "1 board set" simply Yarra. This simplifies counting when some folks also want the Melbourne, etc. I will start sending out invoices soon as there looks like ample interest in the Yarra. If I have your Paypal address already from the concurrent Melbourne GB, I can send you the invoice as you are a repeat Aksa addict. If not, please send me your PayPal address via PM.
Thanks,
