Akai 1710 modification

Hi experts I have an Akai 1710 which I would like to use the amp section and external speakers. I’ve seen many YouTube videos showing this done and with 4wpc and my speakers at 96dB I should get some sweet sound. The tape deck itself doesn’t work that great anymore and no one around me is qualified or experienced in fixing.

Anyway I hooked up my streamer via coaxial to a DAC amp and then took the line out of the DAC and plugged into the line in of the Akai

There is absolutely not sound at all. When I switch the amp to record more then I can see the needles move which tells me the line in circuit is dependent on record mode being on ? But why no sound?

I then took the cables from line in and plugged them in to line out and lo and behold I had sound from the external speakers 1/4 inch jack albeit really low I’m taking maybe 20db.

Before I dismantle it and separate out the tape from the amp.

What do I need to do to activate the amp section when I plug in an input source like a streamer or CD player.

I am also aware that there is a black 4 pin connector plug that links the amp to the tape but not sure how to modify so that the amp itself can be powered.

But yeah if you have any advice on how I can get the amp to output sound that would be great.

Ps I had a valve amp it broke Cost of repair too much can’t afford new one yet so thought why not try this

Ps playback volume during tape play is loud and clear just that it has a tendency to get stuck sometimes and I have another deck now anyway technics rs1500
 
There two versions of the Akai 1710. One uses 6BM8/ECC82 as driver/outputs with ss rectifier, other one has 6AR5 as output, ECC83 driver and valve rectifier. Which version is yours?

To convert into a stand alone amp, remove the tape mechanism and the PCB that carries the tape preamp circuitry. The output of this board is connected to the volume or tone control, sorry I forgot exactly where it goes. Anyway, you connect a sheilded cable from the input RCA to the same point and that is it.
