Title: Question about JTM18 Post by: Marshman on November 17, 2010, 12:02:56 AM Hi there,
I want to do something similar to the JTM18 (fixed bias 18 watt JTM45) - however i want to use 4x EL84 tubes. I was planning on using 36 watt transformers and a GZ34 rectifier tube. Would the top mounted dual 32uf filter cap need to be larger? Would the internal 16uf axial filter cap need to be larger. Do i follow the 100k grid leak resistors, 47k bias resistor and 10k 3 watt resistor as shown on JTM18 thread? Do you think any other components would have to change? Cool forum too! Thanks in advance ;) Title: Re: Question about JTM18 Post by: JohnA on December 17, 2010, 04:03:50 PM If you want a 36W JTM why not just build with 2 KT66's IMO you would lose a lot of what makes the JTM45 so good using EL84's
