Hello.

I'm in a jam. Recently purchased the Fatman iTube Red-i with Speakers It does not come with a headphone output.

* Power Output: 25Wx2
* Frequency Response: 20Hz - 20KHz (±1.5Db)
* Harmonic Distortion: ≤0.5%
* Signal-To-Noise Ratio: ≥86Db
* Input Impedance: 100KΩ
* Output Impedance: 4Ω, 8Ω
* Valve Type: 2x6N1(ECC85)
* 1x6E2(EM87)
* Power Supply: AC100~120V/50~60Hz, AC220~240V/50~60Hz
* Dimensions: Amp: 450x220x210 mm ( WxHxD), Speaker: 330x315x210 mm ( WxHxD)
* Weight: Amp: 5.8kgs, Speaker: 6.8kgs


I am interested in having someone build me an adapter to allow me to power my Sennheiser 580s with the speaker output. Here is a schematic (foreign language to me).

Headphone Adaptor for Power Amplifiers

A switch between the speakers and headphones would be extra sweet.

I have been told that the results can be very good with resistor values designated for a 30 wpc amp. Since only six are needed, I would go for the best quality metal film types I could find (such as Vishay RN series-Digikey and Mouser have them); this will help to ensure that these additional components are as sonically-transparent as possible.

If you think you're up for the job, please pm me or email me at prepwhiz@gmail.com

All cost of parts will be covered and additional for your time
