Sound Dynamics R85 Speakers

 Another speaker currently in storage is this pair of Sound Dynamics R85, these are in a nice Rose wood finish by the looks to me. This pair is good to go as the foams are still good. I have yet to audition these.

Boston Acoustics A150 Speakers

 I have been digging through my locker space today, and figured I would post a few of the projects in waiting.

This beautiful pair of Boston Acoustics A150 MkII came my way. These still need to be refoamed, which I have the foams for. Nice Oak veneer and in perfect condition.

I look forward to getting these up and running on a tube amp.

Camber LS-1 Speakers

So in this Covid hibernation, the little speakers that have been doing duty is this pair of Camber LS-1 speakers. Camber is a Canadian manufacture of speakers and I have have a pair of their Camber 2.5 in the past.

This little pair sports a 6 inch woofer two way system in a sealed acoustic suspension box. These are perfect apartment/condo sized speakers and sound pretty good for my current living space.

These could have easily been a new $200 to $300 dollar speaker. In a small space hooked to a Single ended EL84 tube amp they sound great.

RCA RS-177J Tube Amplifier

 This blog has been super quiet as of late due mostly to Covid and my current space that is not as conducive for expansive audio experience and restoring. That being said I am still finding gear, although much harder to find and it is in storage until a later date.

This nice RCA RS-177J tube amp made my way to me through an Ebay win, the amp was in pretty rough looking condition and needed a serious overhaul including new capacitors, resistors and a general cleaning and a paint job.

This amp seems to have a good reconditioning following on the audio forums, but I mostly followed Mark Walker at Blue Glow Electronics walk through including the front end hot rod modification in changing out the 6FQ7 input tubes to 12AX7 input tubes.

He has a few videos also on the restoration of the RS-177A version of this amp.

I followed Mark's instructions and managed to get this tube amp sounding great. I got all new JJ tubes from the Tube depot.

This amp is from the top of the line console stereos that RCA made in the early 1960's and runs around 12 watts per channel in a push/pull configuration.

These RCA's are worth sourcing out as they are easy to restore and there is lots of info on these. This one is a gift for my son for his 21st birthday, something  he can enjoy for another 50 years.

Audio Nirvana Open Baffle Speakers

Just completed is this pair of Audio Nirvana Super 12 Ferrite Open Baffles.

This pair was my latest version of open baffles and a little more resourceful, the baffles themselves are cupboard doors from a local Restore store for $5.00 each. The base was a end cut of a counter top also found at Restore for $5.00. The cupboard doors had convenient handles built into the cabinet for easier positioning of the baffles.

At any rate this project worked out beautifully, my old Electrohome single ended tube amp is in for repair and I have these hooked  to my Rotel RX-950AX Receiver and they sound wonderful.

These Audio Nirvana 12" full range speakers are simply to die for. I am still waiting to pair this up with one of Audio Nirvana's tube amps which I am raising money for.

So far I have sold enough audio gear myself and have banked $400 towards the purchase of a dream tube amp.

Unitron Speakers

Unitron speakers? Huh? An easy thrift store pass by..... It is what is in the box that the treasures can be found.

This pair caught my eye as the cabinets are in pretty good shape and made of real wood veneer, they do need a bit of sanding and new polish, that is easy work.

I opened these up and found a 10" Coral woofer and Coral Alnico tweeter, I figure the cabinets and the drivers were well worth the low low asking price.

My plan was to find a new home for some 10" Foster Alnico woofers and a tweeter of some sort, these boxes would fit the bill.

 I got these home and listed to them with the Coral's in them, boomy, boxy sound was all I heard. The Q's are too high from the woofer for this box. I pulled them out and inserted the Foster 10" Alnico woofer and a Radio Shack 4" Alnico full range speaker, crossed over with a simple 22uf cap around 900hz. Now these speakers sound delightful, like amazingly delightful.

 

Like amazingly delightful, I am going to do more finishing work on them but I have them up and running and I like what I hear.

I mounted the Corals on a spare baffle board that I had around and gave these a listen....OMG these on a baffle are a completely different speaker. Super efficient, the high Q's add beautiful sounding bass for its size of the woofer and the mids and highs are dreamy delicious. Just as I suspected.

New baffles will be made for these and I will offer them up for sale in the near future.

Raising funds for a new Single Ended tube amp

Do you like the content of this blog?  Want to help contribute to the ongoing musings of a audiophile junkie?

I started a Gofundme link to raise money for a nice new tube amp, my older single ended tube amp seems to be acting up and I am saving up for a new Audio Nirvana EL34 tube amp.

I am also in the process of liquidating much of my current gear to help the funding of the amp.

I believe in an abundant universe and feel that readers of this blog will be generous in their support.

Cheers and thank you for your continued support of visiting this site.
