Elekit TU-8100 as a phones amp !

Hello all,

I just made a DIY voltage divider phones box to use this great class A tube amp kit with phones. Being a 2 Wch amp and not having any high efficiency speakers, I thought it would make a great phones amp. Well it did ! Sounds fantastic with all my low to mid efficiency phones, dynamic and planar. It cost around $55.00 USD. The most expensive parts were the precision resistors. Just four resistors, four multi way spk. posts, a 1/4 “ phono jack and a small plastic project box. I used small Velcro pieces to keep it from sliding off the amp.
The phones are modified Koss KPH30i. I used foam pads for the Grado 1000 or is it 2000 large phones. You simply remove the covering over the drivers and the OEM pads. Cut a slit in the Grado pads for the leads and slip them on. Nice hot weather light weight great sounding phones for around $45.00 all in.
Two easy peezy DIY projects.
