![]() ![]() I’ve taken on some stupid ugly projects and I wouldn’t get into an Ampex 351 project like that. Is it necessary to find something that needs work? If you are interested in a classic broadcast/recording industry tape machine that has a broader base of support, is easier to find, is easier to get going, then why not an Ampex 440? Or just get on Craigslist or eBay and find anything local in a 1/4” halftrack that is running. If this project could count as ALL of your final year project then maybe it would be worth it, but that’s the commitment level you are getting into if you want to take this on. ![]() Find Innovonics replacement electronics (rare, likely in need of work, and then you STILL have to get the transport working right which is highly likely to be expensive and time consuming) Find matching clapped out left for dead 351 electronics and get them working (EXPENSIVE, and complicated.there is a raft of pitfalls and caveats to refurbishing 351 electronics, and they are more dangerous to work on because of the high voltage)Ĭ. Find working 351 electronics (EXPENSIVE)ī. You cannot connect the tape heads to modern low impedance amplifier electronics.the tube stuff was low impedance. Getting a clapped out 351 carcass running right is not for the faint of heart. therefore, a poor condition machine is not nessecerly a drawback, i am not expecting to get a 100% working unit to put in my studio. the final goal is to a create a working example of this fine machine and to thoroughly understand the proccess of magnetic recording & electronics. Important to say that i am looking to buy those as a part of my final year sound diploma project, under the guidance of my electronics teacher. so i assume they were regularly maintained, but might have some mileage on them.therefor buying 3 of them woul'd make a good source for spare parts. They came actually from the national radio auction. ![]() I can see that only Inovonics made an official replacment for the 351's original electronics, but they are rare as the original. what will be the options of replacment amplifiers for those tape recorders? to put it otherwise, what are my options of connecting those machines to let's say, a mixer or other preamp, and not to the orginal one? my major concern is about the interconnections for the different heads, and the transport connection - picture of the back panel of the *missing* preamplifier is attached. putting aside transport condition and such. I am having serious doubts tho as they all miss the electronics. there's extra 150$ for shipping and handling, as it sits at -1 floor and about 45 min drive from my place. A local old man is getting rid of 3 Ampex 351 (one is mono, two are stereo) that are sitting in his garage. ![]()
