JEL SE10 amp

A Harana Audio/JE Labs collaboration

After the November 2009 Hi-Fi Show, a friend commissioned a pair of mono block SE10 amps. Given my busy concert schedule I needed the expertise and assistance of our friend Joey of Harana (Serenade in Filipino) Audio for the chassis and woodwork.

My parents were expecting their first brat...

...me.

The camera originally came with a tripod, self timer and light meter. Apparently this little brat destroyed the light meter which eventually got lost..

Dad taught me the basics of photography on his Penta J with the aid of a Sunny 16 guide found in film boxes.

Lin - classic speaker guru par excellance and Rofiel - mono aficonado

Rofiel found this Jensen M10 field coil 13" driver (OEM WE TA4151 - more info) stashed in an ancient garage 120 kms. away from Manila

I revived the tube rectified  power supply with fresh Sprague ATOM capacitors. Since original replacement cones are unavailable, we took it to Lin for restoration.

The result of Lin's...

...painstaking labor.

To augment the top end, we added a phenolic diaphragm'ed Jensen RP103 alnico horn tweeter through a simple DIY crossover

Rofiel designed a Klangfilm inspired open baffle using phenolic plywood with piano hinged wings to maximize bass yet convenient transport.
