I am new to this site, so please understand my ignorance. I recently came into this near mint '70 SC150. I has the original cover and is a cool Cascade Blue. I am into vinatge gear, mostly guitars and tube amps. I need to find one knob and a replacement CTS speaker for it (one is blown). Othert than that, she can scream! I have no idea if this is a good Kustom or not, other that it is my first exposure. Any thoughts or recommendations? I will poke around here for awhile and listen to some of the veterans! Enjoy the pict! Razz

Hello....and welcome! Very nice amp. I am glad to hear some of them made it to Alaska! The 4x10 SC is, as you said, a "SCREAMER" 75 watts RMS and four tens to make it heard. The size and weight are the ONLY drawbacks to these amps. The clarity and tone make it worth your effort. Buy a cheap two wheel dolly and take it anywhere! Kustoms are usually very clean and transparent amps. If you like using effects they will work very well with the amp.
Someone around here should have some knobs....look at the classifieds or run an ad. Someone should have some spares. You might also find a replacement 10 in classified land. IF not sometimes they show up on Ebay or you can have it reconed.

Congrats on your "First" Kustom....(most of us have several) I know there will be more in the future! BC Cool

Hello, and wellcome.I have the same amp but the earlyer K100 model.When I got mine it also had one blown speaker. These amps want to see a 6 to 8 ohm load, so with the remaining good speakers you could wire 2 in serise and then place the 3rd in parallel for a 5.3 ohm load and the amp will be ok, but here are some suggestions.These amps sound darn nice and if you are going to play out with it you might consider getting 4 new speakers and packing the orignals away. Those orignal CTS speakers are the same models excecpt for the aluminum voice coil cover that came in alot of fender super reverb amps.These vintage alinco magnet 10 inchers are going for any where from 100 to 150 dollars each. These speakers where blown rather easly with the 100 watt head no less your 150 watt head,also all these vintage speakers where put together with animal glue so its just a matter of time and conditions for the voice coil to drop off the cone even if it does not blow out.Also you might want to replace all the orignal knobs with radio shack ones, so you can save the originals.I`ve had all too many times lost my orignal aluminum center incert of a knob at a gig when if fell off. I would get the orignal speaker reconed, but first heat up the edge of the cone and voice coil cover witha hair dryer untill you can peel off the aluminum cover. You can then send it out with the speaker for repair. speaker reconers can not supply a oringinal type cover, so sending them your already removed will let them use it on the new cone assy.
