hi Mygodishendrix!

please, main differencies o know are 1) in/out jackas and footswitch are on the other different sides, 2) different word description of pots and different brand 3) supply differencies (with or without tranny inside)

please, would it be problem to open yours and make photo of back of pcb?? i still didn´t wake it to life it would help me to make me more shure how is this machine connected very much!!

regards,

Yes, i guess it works, yesterday i´ve built stabilized DC 24V/10W power supply for all three boxes(it took them apart, before it they worked fine), next week i´ll try to record some samples with it. Unfortunately, i still do not know additional knob functions, to tell you what they´re meant:((…but that´s the adventure:)))

Hi Julian, the only chips which are inside HT are 4558 and CD4049. Both are avaible and currently in production. I´m to electronics and have build some tube amps and effects including Hot Tubes clone. Now, when i have original i can say it sounds the same as my clone and i used current production chips. Year ago i sent email to ehx with the same question, they told me that Hot Tubes reissue is selling now good and have no interest to produce the old IC version.

Hi there:)

it´s a little adventure for me now to investigate what all the knobs do:)) I don´t know who were the previous owners, who gave there these knobs/possibilities. I play guitar in a band around 14 years and it was always my dream to own IC Hot Tubes (i like Sonic Youth very much and Kim uses one) and also DMM which was kind a mystery for me. However, these effects were too much for my vallet and HT is hard to find. Here, in Czech Republic, the prices are pretty high opposite to US, and $250 (i recount it again from our currency to dollar and it´s $100 less i wrote in my first post, sorry for that) for HT+DMM+Microsynth is 1/3 the price!! Above that all, these effects are equipped with mentioned knobs and effects inside, which i´m exploring now. DMM has only added needle indicator(you can see the level of signal, not only LED overload). Hot Tubes was big surprise. It has added tremolo (unknown producer) and as there was space enough (little HT pcb) there is added three knob Attack Equalizer pcb. Above this, there is in HT case also compressor pcb (unknown producer, it could be Dyna Comp, not sure), but it was controlled from Microsynth two MXR knobs (you see on the left). All the pots are CTS like, all the pcbs are original, i mean not homemade. Microsynth has additional switches and a few knobs i can´t say now what hey are for:) Despite the fact i can put here only 75k images, if anyone is interested in pics i gladly send them on his email (my is mojek(et)centrum.cz).

Yes, and i forget to say, i´ve already dismantled these three effects, DMM works properly (with old supply) and the rest is under reconstruction.

Have a nice and succesfull day!
