Hi there Rasmus, The transformer output is a push-pull power amp and T4,T5 are powertransistors driving the transformer. Trimmer TR1 sets the re...

Hi There Peter It does seem the input transformer in reverbtank could be shorted. I have had one tank do that and it was caused by a metal flan...

Hi there Pter Ah yes my misstake then and as I said above measure output of transfomer under load and you will see... Are you sure tank is...

Hi there Peter, With Oscilliscope you can measure output at secondary of transformer under load and if you have a sine generator you'll see where ma...

Hi Peter, The transformer output is made to drive 8 Ohm tanks so yes it might be too low for 100 Ohm tanks. Ideally if you can find you'd need...

Hi there gents I’ll combine answers below Hej Björn (and others on the forum too)! I had an attempt at building the Universal Reverb kit...

Hi there, OK so at deeper investigation: Firstly slight volume drp when increasing Dwell 1 wasn’t considered a problem because it also gi...

Hi There Mike OK I 'll give this deep thought and may have to build a board and see if I can get this Re J Fet's : no it won't make any au...

Hi there, OK so you still have a problem? I will try to help you figure this out. Re: J Fet’s, those typically have the worst possib...

Hi Mike, Yes I see and yes connections are tight and next to output is B+ et.c. That is great to hear that it is now solved BJ

Hi there, Yes tagging sends me a notification So let’s see how I can help you. Volume at ouput of circuit should be constant regardl...

Hi There, If you want to EQ the reverb the moist strategic point of doing that is before reverb driver and connections to Dwell can be broken an...

Hi There, Thank you, Let’s see how this can be figured out In faultfinding it is always best not to assume just methodically tes...

Hi there, This is a fairly simple circuit so there are limits to what can go wrong. I will try to help as best I can- so hang on in there ...
