i checked the governor and it is secured firmly on both ends such that there is no give when i move it horizontally, but it is free to spin vertically so i can rule that out. there are skidding sounds now and then coming from the motor spring so i can assume that that is the source of the varying speed issue. i'll take it apart once more to give it a more thorough greasing.
also, i managed to get the back of the soundbox open (thankfully without breaking it) and patched up the diaphragm on the front and back. unfortunately the sound is still slightly distorted at the highs and peaks. i just emailed the website Ortho_Fan recommended to me regarding the replacement diaphragm and i'm waiting to see if they could ship me a new diaphragm. but $15USD for a new diaphragm? that can't be true right i thought those things cost way more, maybe there a catch somewhere..
<--- regarding this hose/gasket issue, i suppose i could go and find a tube that fits, but how would i secure it to the soundbox? glue? epoxy?As for the missing back gasket, you might be able to find an appropriate size rubber gasket from your local hardware shop. Even a cut hose of the proper size will work. Try a local auto repair shop or garage and see if they have something that will fit, or can be trimmed to fit.
as usual i'd have to thank everyone (especially Ortho_Fan) with every post i make because each time i think this machine is junked, you guys give me hope that it still can be saved yes, granted it is a common HMV 102, but it would be very satisfying for me to see it working 100% one day
