Akai GX28xD 7" reel to 10.5" reel conversion
Folks, I recently two Akai reel to reel units; GX280D and GX285D. Both units use 7" reels. I could not afford a 10.5" reel machine, as these are selling close to $800 and up and I paid $350 for both my machines. I looked at purchasing an Akai EA-11 adapter kit, but decided that this was not... -

Philips N4420 – Overheating resistors during playback
Hello, I have a Philips N4420 reel-to-reel recorder that works stably, but I’ve noticed a specific issue: -R57 and R396 resistors get very hot during playback (original ones eventually smoked).

Is my tape head ruined?
Hi everyone, I was recently given a Fostex Model 80. Once I got it home I took a look at the rec/play tape head and it appears that one of the gaps is broken but I’m not sure. Does anyone know if this head is damaged beyond repair? If so what are my options for getting it replaced? Thank you!- Kekorepeleco

Help! Pioneer T-6600 (R2R) Won't Go More Than a Second without the Tape Going Slack
I have a (so far as I am aware) previously-unused Pioneer T-6600 I just acquired that is having trouble keeping tape in the tape path, even after replacing all the belts. At first I could not get it to play/FF (it's an auto-reverse deck, so there's no rewind distinct from FF) at all for more... -
