@plasticspoon8 - I can recommend an Audiomods Arm for your Technics SL-1700 mk. 1
Jeff , at audiomods can fabricate a mounting plate for your turntable that makes installation a doddle.
His arms are amazing and will elevate your TT to performance levels equalling some very expensive TT’s.
I purchased the earlier Series 3 arm 12 years ago and have never looked back.
Get the one piece harness with the KLE Innovations RCA plugs and if you change cartridges often, opt for the Micrometer VTA adjustment
It will cost rougly the same as the Rega TT and sound so much better
I use a Soundsmith modified Denon 103 with a Moon LP 5.3 RS phono stage and the sound is extremely detailed, very musical with an amazing 3D image.
Hope that helps - Steve
