Tascam 388 combined reel to reel and 8 track mixer
Before someone brings this 80 lbs weight .84x.22x.64 metre piece of kit
half way across the country for me to repair. Does anyone know whether it is a straightforward job, and how, for the owner to remove the large and heavy glass top for him to leave at home ? -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

Not that big a deal, usually, to get the rear cover off for inspection (but I pray you have a manual?) Rare, but there are a few fuses under that rear cover, you could get real lucky. IMO too much crap in one box, mediocre performance from a transport that's too slow with head track separation that guarantees crosstalk (come on, 8 tracks on a quarter inch of tape?); and that's when they're working properly. Sorry Teac, perfect machine for AM talk radio SM57 mixdowns (as long as you don't need more than 40 db S/N or want to go below 100Hz or above 8Khz.) -Robert QTS http://www.Braught.com |

The actual problem is tape transport, hopefully not motor failure I have a number of Tascam r-t-r technical manuals for the same period |
