Hello, writing from Spain.
A couple days ago I found in an online second hand shop an amplifier exactly like the one in this thread, a Marlboro 220R. It was only 29 euro, so of course even knowing nothing about it I jumped at the opportunity. Should reach my home today. At the very least, I thought, I can use the cabinet to make a tube amp, I've done that in the past.
So of course I started googleing and I found this thread. I may have some questions for you in the future, if that's okay. For now, what intrigues me are those two transformers on the pcb (or they could be chokes). It's very unusual in a solid state amp, at least for me, and I've seen (and made) a few. Can you tell me anything about them?Many thanks and best wishes.

Hello, I never had a schematic, and didn't look into it that much , as I only had the interest in repairing the faults at the time.
I assume that the big xformer is indeed a choke (perhaps they used a choke to regulate the output voltage stability better, as an input choke power supply/or a resonant choke power supply of sorts, although I'm not sure), but the little red one I think is a xformer driving the reverb (this model, in some variants, had a reverb tank attached to it below).
Sorry I can't help more. I really liked this amp....put a DOD250 grey clone in front of it and it screams
Best of luck

Salut. Ma refer la ce care o folosește în momentul de fata live, nu cele de mai de mult
Cum a zis si un coleg mai sus, pare OLP (Musicman like), si multe modificari.
Tremu e o copie ce se afla demult prin anii 80 pe chitare numeroase, si seamana cu un Kahler(nu mai stiu modelu, si vad ca are montat si un fel de D-tuna pt drop tuning)
Nu prea vad cu ce te ajuta ce foloseste...nu are relevanta cu nimic. Daca vrei sa scoti soundu ala de live, mai degraba orienteaza-te spre amp, care este un Laney Ironheart cred, varianta head.

Texal Special, 57/62, Fat 50s, CS54 daca vrei mai vintage. (specialurile si 57/62 sunt most common sa ai iar that original tone sa zicem)
In loc de humbuckeru de bridge chiar nu stiu, multe suna bine split sa compenseze cu cele single middle si neck. Ceva cu alnico ar merge, dat fiind ca si restu sunt alnico de middle si neck. (atomicu oricum e alnico, ai putea sa il pastrezi daca ti se pare OK split, sa nu te complici aiurea).
Spor!

Pai zi asa :D o sa ma uit acasa daca nu am cateva si vorbim pe privat. Parca am un set desperecheat de 5 ramase. Will see

Esti sigur ca suruburile sunt problema?Spun asta pentru ca si alea ieftine, nu se duc usor deloc. Ce inseamna sunt bufnite? La filet sau la hex side?
In general la ce descrii tu, s-a stripuit filetul de la SADDLE, si nu surubul. (saddleurile daca nu sunt de steel la modelul tau si sunt aliaj, pot pati asta foarte usor de la suprastrangere, iar eu nu am vazut pana acum suruburi de otel de lock stripped de saddle de aliaj...).
Fa o poza la suruburile afectate, si verifica cu un magnet daca se prinde de saddles sau nu.

Schallerul Germany are spatierea adecvata pt ''poza 2''
-
Nu, pentru ca spatiul nu este suficient(daca ai base similar cu cel de mai jos) pt cei din ''poza 2'', fizic nu este loc.

* Harley Benton GA-120H Solid State head cleanup
* Had a Stagg Acoustic in, that had multiple issues and now are solved
* Dunlop 535Q wah in for some connectivity issues
* Squier Bullet Strat Indo setup and nut changed to left handed
* Had an early 80's US Fender Lead I in for a setup
For Fun:

Mersi MULT de raspuns, o sa incerc sa le schimb eu
Imi era frica de "bias" ca nu stiu exact ce ii, si nu as vrea sa stric ampul.
O sa scriu aici daca am reusit ceva sau daca a "explodat"
Iei altu, da-le dreacu
O mentiune, daca observi dupa ce ai montat finalii ca fac cumva asta(oricare din ei), stinge-l imediat.
Normally ar trebui sa fie OK, si sa nu ai probleme.
Best of luck
