Hi-Fi Project Advice

Solid State - diyAudio - www.diyaudio.com
Hey, everyone- new member here. I've been interested in music and audio for over a decade but recently have a reason to get my hands dirty with some DIY projects. I'm a (rusty) electrical engineer with woodworking and solder skills. I have access to a basic machine shop with a drill press, lathe, sheer, welding equipment, etc.

I picked up a "Wards" audio cabinet for $10 from a thrift store which includes a turntable, FM radio, amplifier, 2 x 12" Woofers, 4 x 4" mids, and possibly some tweeters, though I'd have to look inside again to verify if there are tweeters. If there aren't any, I'll probably add some.

The cabinet itself has a lid that opens, exposing the turntable and FM radio tuner. The amp and speakers are hidden inside of the cabinet. The rough internal dimensions of the cabinet are 48" x 12" x 18". None of the original electronics work, so I'm looking at refurbishing it with a new turntable, pre-amp, amp, drivers, and a networked media player.

Here's my proposed solution:

Turntable: Pro-Ject Debut Carbon (one of the few that fits the space)

Pre-Amp: Modified Yaqin MS-23B (unless I can be convinced to build an APEX model, though I like the asthetics of the tube design)

Amp: *need advice on one of the 50W/100W APEX designed amplifiers*

Woofers: Dayton DS315-8-12

Mids: Dayton RS100-4

Tweeters: Dayton DC28FS-8

Crossover: Custom design (future part of the project)

Media Player: Raspberry Pi w/ Hi-fi berry DAC to play lossless audio and Airplay audio over the network

I listen to a wide range of music and am of power. This will be something that I'm likely to keep and use for years to come and want to do it right.

I plan to have a two-position rotary switch to cycle the amplifier input between the Rpi and the turntable.

I appreciate any help or feedback and hope to post pictures shortly.
