Grommes G101-A rebuild Simply Amazing!

Description

See the before pics vs. after.

I had an NOS pair of these amps years ago and have always been sorry that I sold them. I found a beat up pair and have taken nearly 2 years to figure out how I wanted to restore them. Scrapped the rack mounts and face plates, replaced the jacks with gold 5 way posts and gold rca's, original paper caps were replaced with JJ. Amazing sound. I've had AR, Threshold, Sumo, PSE, Dynaco and more in this system and the Grommes are by far the best!

For simplicity, the Trio works fine for my family running little Soliloquys. I had it completely modded by Chris Johnson at Parts Connexion. The pre and cd are now amazing. Chris upgraded the pre-outs for me so I could run external amps. The tuner is nice, has in/out for video too if I want to run the tv through it. Great headphone system also.

The PS Audio helps a lot. Cabling changes all the time from Nordost to Kimber to JPS.

- Grommes-Precision G101-A
Mono block tube amps. 6GT5 output tubes, 12at7 gain and 0A2 rectifier. 100/120wpc can drive down to 1.4 ohms continuous. Fast, crisp sound, not "tubey" and bloated sounding at all. I just finished a complete rebuild on these amps, cosmetically and sonically. The tech I took them to for the final biasing thought I was nuts until he got them on his bench. After retubing, biasing, regrounding and a few repairs, the test results were phenomenal. At full volume, 100 watts continuous, they are dead silent, running about 1.8% thd, extremely square wave from 8Hz all the way to 25Khz. He said that the only other tube amps he has ever seen with this kind of test results are $10k Mac amps.

I replaced my Sherbourne Pre and Cambridge 640p with a nice old PSE preamp with built in phono. The quality of PSE equipment is amazing. Simplifying my system helped a lot. Eventually, I will have some minor mods done to this but so far it has impressed me.

Hello Elevick,

I came across your post reading the SOTA table and wondering whether you can provide the instruction for service the SOTA table to remove the platter and adjust the motor. Please kindly advise. Thanks for your kind assistance.

I've got the instructions to remove the platter and instructions to adjust motor slipping. Email me if you want them-it's not easy. [email protected]

Regards,

Will
