I got the new ten section ten Henry chokes built and cryo treated. I installed them and was able to compare the sound to that of the two Hammond seven Henry chokes which had been in series for a total of fourteen Henries. The new ten Henry chokes sound better. They are built up from ten one Henry chokes connected in series and physically spaced. Each choke is mounted at right angles to the next in a line. The chokes were bought from surplus and were very inexpensive. Remember that the choke goes in series with the high voltage output after the load resistor and before the diaphragm. Give this mod a try and I am sure that you will be very pleased with the results. Best regards Moray James.
