Gerben	Re: Fender to "D-word",anyone? I’m interested in which schem you used. I have one from 1977 and from 1997. So: 1. What did you use as plate/cathode resistors: the “old” 100k/1K5 or the newer version which uses higher values. Does the newer version have more gain? 2. EQ-clean. Which values for the pots and resistors in the clean-channel? Have you tried the “deep”-switch? What does this do, boost bass? 3. EQ-drive. Did you use trimpots or fullsize-frontpanel-mounted pots. Which values to use for the capacitors in this section? 4. Suggestion for capacitor-types in the tone sections? 5. Presence. Is it really usefull? E.q. I always turn it down on a Marshall: too bright. 6. Powersupply-filtering: Lots of uF in the newer version. Since I which to use a SF Twin, the old PS-setup (2x 100 uF/4x 20 uF) would be easier to use. What is the effect of using less/more filtering on the PS? What would be your suggestion? 7. Powersupply-voltages: do you have exactly the same voltages as given in the schematics? Is it a ‘must’ to have the same voltages, what is % tolerance? Your help, and other suggestions, are really appreciated! Gerben

Re: Fender to "D-word",anyone?

I’m interested in which schem you used. I have one from 1977 and from 1997. So:

1. What did you use as plate/cathode resistors: the “old” 100k/1K5 or the newer version which uses higher values. Does the newer version have more gain?
2. EQ-clean. Which values for the pots and resistors in the clean-channel? Have you tried the “deep”-switch? What does this do, boost bass?
3. EQ-drive. Did you use trimpots or fullsize-frontpanel-mounted pots. Which values to use for the capacitors in this section?
4. Suggestion for capacitor-types in the tone sections?
5. Presence. Is it really usefull? E.q. I always turn it down on a Marshall: too bright.
6. Powersupply-filtering: Lots of uF in the newer version. Since I which to use a SF Twin, the old PS-setup (2x 100 uF/4x 20 uF) would be easier to use. What is the effect of using less/more filtering on the PS? What would be your suggestion?

Your help, and other suggestions, are really appreciated!
