She looks good early version with solid shelf under amp rather than aluminium stripSemi open rear (later ones were closed cab) what is the band name marked over.. four letters?Nice fine Celestion G12H speakers with a simple HH sticker over them and they sound great!Slightly differnet colour plastic on this one.. must check date codesNice leg feature for using the combo as a monitor!Great foot switch for Reverb and TremoloLovely side lit control panel. She sould great with a Les Paul soooo T.Rex!Top out ready for service.. one or two new pots requiredGut shot.. Torroidal and power amp board and pre ampboard at the frontInteresting mass of contact adhesive not holding the cap on well 😉Could not resist cleaning the HH label off to see which Celestion speaker it really is.. and a G12H 30 watt! I lost 5 watts taking the label off!Interesting differences. The silver dome is a bit more custom for HH I believeG12HG12H4th May 1973Dust coverYou can see through it! Grey cover from late 73Interesting different dust cover on the HH branded one. Though I think there is still a Celestion label under the HH one20th December 19732 Carvin 100 Watters to put in these are 8 Ohm so togeterh will give 4 Ohms ideal for the ampFitted! look good in black!Back on ready to try!Bottom of the combo with damaged (worn out..) Castors Bottom cleaned and New Black Castors fitted!All cleaned up and sounding great!New knobs.. not the same style but I think look good (originals hard to come by)Copper coloured knobs look good with this old a,p IMHOAfter playing for while with the Carvin speakers I decided the original ones were a better match for the amplifier, though a bit light on wattage they had survived since the 70s so should be able to take it! Nice IC100 by HH from 1973 purchased at a really low price. These are great amps with a fantastic sounding built in Sustain or fuzz circuit. Using op amps she sound unique. This one was fitted with 2 x G12H speakers from Celestion.. but these are a bit low rated for the 100 Watt amp (and looks like one was replaced in late 73 (my guess is one blew). I replaced the speakers for some higher wattage ones that can take the power and also gove a 4 ohm impedance which will get the best out of the amplifier. Cleaned up the cab put new cups on the 4 chassis securing screws (these were missing). She is sounding great, the Trem and Reverb are excellent, sounds very good for an early IC amp. Anyone have one of these that is not working I would love to work on her, I have full schematics for the whole range.
