hi everyone, i have an isp decimator g pro rack guitar version, for my marshall 9200, jmp1, jfx 1 configuration i would need the stereo mod version, i tried to look for used ones, but i couldn't find any. Opening the frame of my decimator I noticed that there is the possibility to convert it from guitar to stereo and vice versa.
I've been watching with (originally) sum scepticism on the mic mods but I just watched and listened to the MXL Marco swapped the capsule in, and have started to think a bit. The 47 diaphragm the Chinese are making pops up quite often, and in every case - it seems to get positive comment.
6 Klark Tecknik DN27A in for work. Its amazing to me the changes over the years. 2 units have input transformers and output transformers. The two will transformers will get a electrolytic cap change and general inspection. Of the four remaining, the most similar two will get Jensen input and output transformers, cap change and inspection.
I'm setting up a converted garage to record voice. The room dimensions are 22'9" x 23'2", with an eight-foot ceiling.
I live near an industrial property that produces noise. In particular, there is the sound of a piece of industrial machinery at around 240Hz, and the back-up warning beeping of construction vehicles.
So I was so interested in the 1612 Tubes I got to play with... I started a hybrid design. The concept is a vari-mu style compressor using the 1612 as the front end after a Jensen XFMR. I am thinking of then running LA2 style buffer and driver amplifier into a Jensen output XFMR. But the side chain will be solid state and use either a LOG amp or a THAT audio engine..
This 900a Series is in to get TRS jacks in to replace the terminal connectors. I made a Custom PCB to replace the board mount terminal connector and reuse the original metal work with a 3D printed mounting plate.
Working on two of these beauties right now. Nice design, nice PCB layout. The customer wants new caps, a few power supply repairs and to add Jensen input and output transformers to these normally unbalanced units. The 160 (the famous unit) uses the same PCB as the 161 but a has a solid state balanced input and output circuit populated. This mod, IMO, is way better ;)
I also had a chance work on this finely built piece. This unit is very cool for making subtle delay/modulation effects. The unit on the bench had a blown output amplifier. I added a opa627 with a slight modification and she is working again.
I have now repaired and Modded 4 LA4's for the same customer. VU repairs, matching the LDR's for stereo pairs, new opamps, recapping and general clean and lubing of the pots.
