Manufatured a Tube Reverb Unit on the base of the tt reverb kit from Tube Town. The RJH Valverb Shines with an interesting unusal tube rectifying method. Have fun!
Nice built!! I made one to,sounds nice,one thing about your power-supply ,with a EZ81 the max elco after the EZ is 47uF,not 100uF ,the EZ will not survive that.
Thanks for your comments! I do not believe everything the internet says about valve technics.... haha.... the exact opposite has been shown in my first experiments with this EZ setup. The 47uF was not enough. Has something to do with the two diodes in the artificial center tap of the so called half wave rectifier setup. Works fine so far. I would recomment the longer reverb time can.
Thanks! Yes - the same transformers. Use the image at 3:09 if you want to implement the tube rectification circuit. The schematic has changed somewhat since then - you find it on the tube town website - so you have to consider some thinkering... Good luck!
Super Sache! Das Kit ist unterwegs zu mir. Würdest Du evtl. den Teil mit der Gleichrichtungsplatine und dem Röhrensockel machen...Wir werden uns da schon einig 💲💲💲
Nice build ! I am trying to somehow mod the nowadays layout. I tried to raise the R11 to 220K as you have and i get crazy oscilations. Maybe if you could somehow explain to me how did you choose those values. The grid leak resistor R11 is in TT layout 33K.
This seems to be the value how it would have been used in the original Fender unit with a 6K6. Make shure you got the 12aT7 in the right position (input). Be aware that the new circuit uses much higher voltage at the EL844 anode (which is a good thing) and I used a tube rectifier with lower B+ at the anode. We do not know if anything else is changed. Could also be an other reverb transformer in this kit now.. Good luck
but on the new board only R11 is different value from what your changes and also on your schematic it says B1+ instead of B3+ like on the new board. May you please advise? here's the new boards schematic. www.tube-town.net/cms/userfiles/downloads/kit-tubereverb.pdf I really want to have the reverb rectified like yours.
@@loganexcelsior8684 indeed a good comment. This video was based on the former reverb kit from TT which is now outdated with this circuit board based version you linked. I used a completely different PSU therefore the B+ voltages differ from my version. In the TT PSU kit neither B2+ nor B1+ is used. Only B3+ is used. In my schematic B1+ is used to feed the plate of V3 and the reverb transformer. 2:40 The other tap isn´t usable.
